Lechia Gdansk

The club was founded on 7 August 1945 in Gdańsk and was originally named "BOP Baltia Gdańsk". The club was first established by the "Port Reconstruction Office" (Polish: Biuro Odbudowy Portów). The BOP's purpose was to help rebuild Polish sea ports which were destroyed during World War II, and saw it best to create a sports club for the BOP workers. BOP Baltia's first game came on 2 September 1945, in which they lost the game 6–4 against Milicyjny Klub Sportowy z Wrzeszcza (Militia Sports Club from Wrzeszcz) in a friendly. BOP Baltia's first league game was a week later and played against WKS 16 Dywizji (Military Sports Club of the 16th Division). Due to the disruption of football in Poland due to the war the first season back was focused on regional qualifying for leagues to reformat the Polish football leagues. In the Gdańsk regional qualifying Lechia won all 6 games including both games in their first Gdańsk Derby games against Gedania Gdańsk, winning the group and being promoted to the A Klasa (A Class, the second division in Poland at the time).

Towards the end of February 1946, BOP officials had a meeting, in which it was decided that the name of the club should be changed. The team became known as "Sports Club for the Port Reconstruction Office Lechia Gdańsk" (Polish: Klub Sportowy Biura Odbudowy Portów Lechia Gdańsk), 'Lechia' coming from Lechia Lwów, as a majority of the workers at BOP and those who studied at the Gdańsk University of Technology had been expelled from Lwów at the end of WW2.

Lechia fared well in its early years in the lower divisions finishing top of their district championships in both the 1946–47 and 1947–48 seasons. For Lechia to be promoted to the top division they needed to win additional qualifying rounds against the other district champions, playing a series of games in playoff games, before a final playoff league with four teams of five being promoted. In the playoffs for the 1946–47 season Lechia finished bottom of the playoff league, being the only team not to advance to the top division. Lechia's fortunes changed the following season however and achieved promotion at the end of the 1947–48 season when they finished top of the promotion playoffs league.

In 1949 Lechia played in the top flight for the first time (at this time the top division was called the "I liga"). While it was a historic year for the club, and showed the competitiveness of the team in their early years to play in the top division, it was not a season to be enjoyed by Lechia in terms of on field performances, winning only 4 games all season and losing an incredible 15 times out of 22 games, finishing bottom of the league as a result. Due to suffering relegation in their first Ekstraklasa season the club found themselves back in the second tier of Polish football in 1950. Their first year in the II liga was a year of transition and the team initially struggled finishing 6th out of 10 teams, and finding themselves way off the pace for an immediate return to the top division. The league format of the II liga was changed for the 1951 season, where in the previous season the division was split into two groups with both winners being promoted, the 1951 season saw the II liga being split into four groups with the group winners playing each other in a mini playoff league with the top two being promoted to the Ekstraklasa. Lechia won their group which was the most diverse group at the time, playing against teams in Poznań and Wrocław who were both across the country from Gdańsk. The team advanced to the playoff league and came up against OWKS Kraków, Górnik Wałbrzych and Gwardia Warsaw, winning the playoffs group on goal difference and being promoted back to the I liga with OWKS Kraków.

The 1952 season was an unusual one due to the 1952 Summer Olympics in Helsinki. The start of the league was delayed due to the preparation of forming a team to go to the Olympics. As a result of this the Young Leaders Rally Cup was organised, and was the first League Cup in Polish football. The organising of the cup was to give the players an opportunity to show off their skills, and with a more relaxed competition compared to the league would provide the Polish team with the best possible preparation to perform well at the Olympics. The cup ran from April – July and initially saw two groups where each team played each other twice, with the top three teams in each group going through to the playoffs to decide the winner and the final standings. Lechia finished 3rd in their group and thus played against Lech Poznań who also finished 3rd in their group to play in the 5th placed playoff. Lech won the game 2–1, meaning Lechia finished in 6th place overall in the Young Leaders Rally Cup. After the Olympics, in which Poland were knocked out in the first round, the league officially started, around five months later than it usually would. The league took a similar format to the cup, with the teams being split into two groups, with the two winners playing each other to decide on that years champions. Lechia finished the disruptive season in 7th place, ensuing they remained in the league for the following season. The 1953 season returned to normality with one league and each team playing each other twice. The season saw Lechia struggle and finish bottom of the league, and were again relegated from the top division finding the increased level of competitiveness difficult to deal with over the course of a full season.

Being back in the II liga Lechia once again found themselves to be competitive. While the club struggled more so than the teams around them in terms of scoring goals, Lechia were the best team defensively in the league, shown by their ability to keep clean sheets, having 12 clean sheets in their 20 games. The team finished the season on 28 points, the same as Stal Sosnowiec who ended up winning the league, but found themselves finish in second place due in part to Stal scoring 10 more goals than Lechia and having a much better goal difference. The immediate promotion and return to the I liga showed that at the time the club were in a position where they were competitive, but too good for the second division, yet struggled against the much better organised clubs in the first division.

Upon Lechias return to the Ekstraklasa, the players involved during these years and the initial success of the team upon their return to the I liga, were therefore seen as being the club's "golden years" of their early history. Players such as Bogdan Adamczyk, Henryk Gronowski, Robert Gronowski, Roman Korynt, Hubert Kusz, Czesław Lenc, Czesław Nowicki, and Roman Rogocz, all of whom had long playing careers with Lechia, were all important in making the club competitive upon their return to the league. Their first season back, 1955, was at the time the club's most successful season in their history. On their way to a 5th-place finish in the league, their highest at that point, they beat strong teams at the time such as ŁKS Łódź, Lech Poznań, Zagłębie Sosnowiec, and the 1955 Polish champions Legia Warsaw. The season also provided the chance for the club's first piece of silverware by reaching the Polish Cup final for the first time. Lechia's route in the Polish Cup (Polish: Puchar Polski) to the final saw them beating Sandecja Nowy Sącz, Wisła Kraków, Odra Opole and Gwardia Warsaw. The final saw Lechia play Legia Warsaw at the Polish Army Stadium, Legia's home stadium. Lechia lost the game 5–0 after a hat-trick from Kempny, and a goal each from Pohl and Słaboszowski seeing them finish as runners-up in the cup, and only the second team formed after the Second World War to feature in the Polish Cup final.

In the league, the 1956 season was more successful than the year prior, seeing Lechia finish on the podium for the first time, with the club also becoming the first formed after the war to finish in the top three. Despite only scoring 25 goals in 22 games, Lechia finished the season in 3rd place. The club relied heavily on their defence that season keeping 10 clean sheets and conceding only 21, the second lowest in the league that season, while their highest goal scorer was Rogocz who scored only 7 for the club that season in the league. The achievement of 3rd place happened under the guidance of Tadeusz Foryś, arguably Lechia's greatest manager in their earlier years, seeing them promoted from the second tier, taking them to a cup final, and achieving their highest finish of 3rd place.

The following season saw Lechia remaining competitive, but with the defensive side of the team not performing as well for the team as they went on to finish in 5th place. Once again the team only scored 25 goals in 22 games, the joint second lowest in the league, and the only team to not score more than 25 goals to not be relegated. Despite only scoring 25 goals that season in the league the team did see a player scoring the club's first hat-trick in the top division, with Bronisław Szlagowski scoring 3 in a 5–0 win over Zagłębie Sosnowiec. While defensively the team wasn't as strong as in 1956, the 29 goals they conceded, which was still among the better sides in the division, ensured the team finished in the top half of the league for a third successive season. At the end of the season, Tadeusz Foryś, who saw Lechia's rise from the II liga to being a challenger for the top places in the I liga, left Lechia to manage Arka Gdynia.

Following the departure of Foryś who made Lechia defensively strong, the team's fortunes declined from the season with one notable difference from the previous season being the number of goals the team conceded. The side fell to 8th place, just surviving relegation by a single point. This was a trend which was to continue for Lechia. While the team improved to finish 6th in the 1959 season, the team only managed to score 19 goals in their 22 games, with only one team scoring fewer, Stal Sosnowiec, who finished bottom of the league. The next three seasons saw the team flirting with relegation, finishing 9th in 1960, scoring the joint fewest in the league and surviving relegation by a point, 8th in 1961, scoring the joint second least in the league but surviving more comfortably by 5 points, and finishing 9th again in 1962. The 1962 saw a change in the league format, with the season changing from a summer league (playing from spring-autumn) to it becoming a winter league (playing autumn-spring). The league for that season was therefore shorter, with teams playing a total of 13 games, 12 in a mini league, and once in a playoff game to formalise the final standings.

Over these years where Lechia struggled, some of the players who were important in the club's rise during the early and mid 1950s started to move away or retire. Henryk Gronowski initially left in 1961, but later returned over the summer in 1963, his brother, and one of Lechia's most important forwards for Lechia during this era, Robert Gronowski, left in 1960, the ever present defenders Hubert Kusz and Czesław Lenc left in 1960 and 1962, and Roman Rogocz, who scored more than 100 goals for Lechia during his 15-year career at the club, retired in 1962. Each of these players made more than 100 appearances in the I liga for Lechia, leaving Lechia without the quality and experience these players provided. This loss of quality was evident during the 1962-63 season which ended up being a difficult one for Lechia. In the 26 games that season, they only managed to win 6, drawing 3, with the side losing 17, scoring only 20 goals, and conceding 48. This caused the team to finish second from bottom, being 4 points from safety, and were relegated from the Ekstraklasa with Lech Poznań, ending their 9 season long spell of continuous top division football.

While some of Lechia's important players remained at the club after their relegation, including long serving players such as; Bogdan Adamczyk, Jerzy Apolewicz, Janusz Charczuk, Roman Korynt, Czesław Nowicki, Zbigniew Żemojtel, and the return of Henryk Gronowski after the club's relegation, the squad struggled to adapt to falling down a division. That season Lechia lost more games than they managed to win, and were only able to secure a 10th-placed finish out of 16 teams. Lechia did adapt to the new division better than Lech Poznań however who suffered back to back relegations, showing the rise in competitiveness since the last time Lechia were in the II liga.

From their second season Lechia had adapted to the league and increased their competitiveness, finding themselves in 7th for the 1964–65 season. This season saw Lechia playing Arka Gdynia for the first time, with the two clubs quickly becoming fierce rivals and leading to the Tricity Derby. Lechia won the first ever meeting between the two clubs with the game finishing 2–1. The club also saw in improvement the following year by finishing in 6th for the 1965–66 season. While these seasons were an improvement on their first season back in the second tier, Lechia never found themselves more than 4 points clear from relegation, the equivalent of 2 wins during that period. This shows that while Lechia were finishing in the mid-table, they were only one bad season, or one bad run of games from finishing in the relegation zone.

This possibility of a bad run of games leading to Lechia being relegated became a reality in the 1966–67 season, which saw a winless run of 8 games, including a run of 5 straight defeats without scoring a goal in this run. Lechia were relegated by a single point at the end of the season, and were to be playing in the third tier for the first time in their history.

Lechia will have expected to be competitive following their fall to the III liga, and the team proved that they could be. Their first season saw them finishing in 2nd, however they were clear behind Arkonia Szczecin, and although they did finish in 2nd place, only the league winners from the four groups of the third division were promoted. The 1967–68 season also saw Lechia's first Gdańsk Derby with Stoczniowiec Gdańsk, despite both teams being formed in 1945 it took 22 years before they met in a competitive setting. Stoczniowiec won the first derby between the two clubs 2–1, in a derby that would go on to be played often over the next two decades. At the end of the season, the long serving forward who had three spells with Lechia, Bogdan Adamczyk, retired from playing football. Adamczyk was the last remaining player who had featured for the club during their "Golden Years" the decade before. Although one club legend retired, the following season saw the introduction of Zdzisław Puszkarz, a youngster from the Lechia academy, who would one day become a club legend himself. The season didn't go as planned for Lechia, with the team finishing in 5th, and seeing their rivals Arka top the league.

Over the next three years however Lechia maintained a consistent challenge on fighting for the league title. The 1968–69 season saw Lechia finishing in 3rd place, conceding only 18 in 30 league games, and keeping an impressive 18 clean sheets. Lechia were still off the pace needed to mount a challenge for a title, but the club had seen improvements since the previous season. The next season Lechia had improved to a 2nd-placed finish, losing only 3 games all season, including losing to eventual champions Lech Poznań, and finishing only 1 point behind Lech, meaning the loss to Lech in the penultimate game of the season may have cost Lechia's chance of winning the league themselves. Lechia did not have to wait long however to win the league for themselves and make a return to the II liga. In the 1971–72 season Lechia won 22 of their 30 games, clearly winning the league with having a 9-point gap to Stoczniowiec in 2nd place, having the second best attack in the league, and by far the best defence in the league conceding only 13 goals and keeping 21 clean sheets, this despite the fact that of the 4 league defeats that season, 3 of them came in Lechia's first 4 league games.

After finding themselves in the second division Lechia performed well and comfortably finished above the relegation zone in 7th place, winning and losing 9 games each over the season, and drawing 12, of which 8 were 0–0 draws. This followed the trend of Lechia not scoring many, but being set up well defensively, with the high number of extra points picked up from draws helping them to finish clear of the bottom 4. The 1973–74 season saw a change of format in the II liga, which was originally just a single league of 16 teams. From this season the division was split into two leagues of 16 teams each and 32 teams in total, a Northern group and a Southern group, with Lechia being placed in the Northern group. This change made it harder for teams to gain promotion from the division as they now had to win the league, where as before finishing as runners-up was good enough for promotion to the I liga. Lechia finished 4th in the league, in what was generally an average season for the team, but due to the top 3 teams taking so many points from the lower placed teams in the league Lechia recorded a high finish, with players such as Tomasz Korynt and Andrzej Głownia having standout seasons.

The 1974–75 season saw a vast improvement from the team, winning 16 of their 30 games, and losing only 6. The club also improved in goals scored, while also being the joint best team defensively. Tomasz Korynt, Leonard Radowski, and Zdzisław Puszkarz each managed 8 goals in the league that season as Lechia went on to finish in 2nd place, only 2 points of the league winners Widzew Łódź. This season also saw Zdzisław Puszkarz called up to the Poland national team to play against East Germany, despite Lechia playing in the second division. The following season was a good season for the Tricity region with the 4 teams in the league from the region all finishing in the top 5 places. Once again Lechia had a strong season, this time only losing 4 games, but again finished in 2nd place, this time 3 points behind rivals Arka Gdynia. 1976–77 was a little blip in Lechia's run of high finishing seasons, managing 5th in the league, and their lowest finish since the league split into two groups. Lechia resumed their title fight from the following season, being the clear best team in the league along with Gwardia Warsaw, with both teams recording over 20 wins and losing only 2 games all season, and finishing nearly 20 points clear of Bałtyk Gdynia in 3rd place. Krzysztof Matuszewski also recorded 15 goals over the season, among the highest in the league. While Lechia were close to winning the league, it was once again not enough, with the club being a single point from winning the league.

From the 1978–79 season the leagues were changed from a Northern and Southern group to Eastern and Western groups. The change didn't initially impact the club, with Lechia finishing in 3rd place, missing out on promotion by a single point for the second successive season. Lechia also went on a cup run, playing Gryf Słupsk, Wielim Szczecinek, Widzew Łódź, and Unia Tarnów on their way to reaching the quarterfinals. Lechia lost in the quarterfinals to eventual runners-up Wisła Kraków. Lechia's fortunes in the II liga did start to change, and after narrowly missing out on promotion in four of the last five seasons, the club found themselves slipping down into mid-table finishes the next two seasons. 6th and 7th-placed finishes in seasons where Lechia nearly won, drew and lost the same number of games each time saw the club looking far less competitive and saw the departure of talismanic midfielder Zdzisław Puszkarz in 1981. It was evident in 1981–82 that Puszkarz, a lifelong Lechia fan and a player who had been seen as too good for the second tier for many years, hugely contributed to the club's fortunes and was irreplaceable for the team on the pitch. Lechia fell to 14th after winning only 6 of their 30 games, scored only 19 goals, and ended up 7 points from safety. Lechia were relegated to the third tier, this time without any star players or big names to help the club out.

Although Lechia found themselves in the third tier for the 1982–83 season, it turned out to be a historic year for the club, and was seen as the club's 'rebirth'. The team finished top of their division, going on to concede only 9 goals in their 26 games. Due to Lechia being in the third tier they joined the Polish Cup in the second round. The first game of the competition saw them play Start Radziejow, who they narrowly beat 3–2 on penalties. The cup saw them playing 4 Ekstraklasa teams on their route to the final. They beat Widzew Łódź 5–4 on penalties, after drawing 1–1, Śląsk Wrocław 3–0 in the round of 16, Zagłębie Sosnowiec 1–0 in the quarter-finals, and Ruch Chorzów in the semi-finals 4–3 on penalties. The final saw them playing Piast Gliwice who were in the second tier. They won the final 2–1 with goals from Krzysztof Górski and Marek Kowalczyk to win their first-ever piece of silverware.

In 1983–84 Lechia were again in the second tier (west group), and qualified for the Polish Super Cup (Polish: SuperPuchar Polski) due to winning the Polish Cup the season before. It was the first-ever season of the Super Cup, and saw the cup winning team play the Ekstraklasa champions, resulting in Lechia playing Lech Poznań. Despite Lech being heavy favourites Lechia won the Super Cup with a late goal from Jerzy Kruszczyński. This resulted in 1983 being the most successful season in the club's history up to that point, with the team winning both cup competitions it participated in despite not being in the top division. Lechia's stay out of the Ekstraklasa wasn't to last long, however, with the team winning the 1983–84 II Liga season, and as a result were promoted back to the Ekstraklasa. A division they had narrowly missed out of playing in many seasons before, and was their first time back in the top tier for 21 seasons. That season Lechia also qualified for the UEFA Cup Winners' Cup due to winning the Polish Cup the season before. In the first round, Lechia was drawn to Italian footballing giants, Juventus. The first game was played in Turin, Italy, with Juventus easily winning 7–0. With the team knowing they were all but knocked out already the team put on an inspiring performance scoring 2 goals against the European giants in the home leg of the competition. The Lechia home game against Juventus was not only a sporting spectacle, but proved to be a place of mass demonstration for the Solidarity movement, which many fans were part of. In the 40,000 crowd was Lech Wałęsa, with the crowds chants of "Solidarność! Solidarność! Solidarność!" causing the second half to be delayed by 6 minutes and with broadcasters resulting to mute the whole second half of the TVs broadcast. The Lechia manager, Jerzy Jastrzębowski, said of the event; "We were in the dressing room during half-time when we heard it and it sent shivers down our spines, the whole ground singing 'Solidarnosc'."

For the 1984–85 Ekstraklasa season, a season in which all teams struggled for goals (an average of 1 goal a game), Lechia finished 12th having scored 23 goals, and with only 2 of their wins that season coming from scoring 2 more goals than their opponents. The season after Lechia finished just above the relegation zone by a single point, and seeing local rivals Bałtyk Gdynia getting relegated a place below. Lechia was lucky that season, with the team finishing 3rd from bottom, with four teams normally getting relegated. However, a change to the division below saw only 2 teams going down that season. 1986–87 saw the team once again fighting relegation. For the 3rd season in a row, Lechia only managed 23 goals in their league 30 games, however, the team once again stayed up finishing in 11th. The team were once more fighting a relegation battle during the 1987-88 season. Lechia legend Puszkarz rejoined the team after having left 5 seasons prior. It had always been his dream to play for Lechia in the top flight, and this was the season where he achieved this accomplishment however it didn't go according to plan. Despite the team finishing in 12th, which would normally be one position above the relegation zone, for that season though there was a relegation playoff, with 14th playing 11th, and 13th playing 12th. Lechia played Olimpia Poznań in the relegation playoff and lost over both legs 3–2 on aggregate. This saw Lechia being relegated with Zagłębie Lubin, the other team who would otherwise have normally been safe also suffered relegation after they lost both legs 4–3 to Górnik Wałbrzych on aggregate. The following season the relegation playoffs in the Ekstraklasa were scrapped.

After relegation from the Ekstraklasa, Lechia found themselves back in the II liga. During the 1988–89 season Lechia struggled to adapt to the new league, finishing 10th out of 16. Things failed to improve for Lechia during the next two seasons, finishing both 11th and 12th. The situation slightly improved for Lechia during the 1991–92 and the 1993–94 seasons finishing in 8th before their highest finish of 6th since being relegated. During this period there was a greater rivalry with the three major Tricity clubs, Lechia representing Gdańsk, with Arka and Bałtyk from Gdynia. The 1993–94 season was an important season for the Tricity teams. Bałtyk Gdynia finished highest in the league for the 3rd season in a row, while both Lechia and Arka faced each other for the first time in history in the 1993–94 Polish Cup, with Arka winning the match 1–0. The season was another difficult one for Lechia, in which they finished 14th, 1 place above the relegation zone. The struggles for Lechia reached a devastating end by the end of the 1994–95 season, with the team, ultimately being relegated to the 3rd Division, along with fellow rivals Arka Gdynia.

The 1995–96 season saw Lechia merge with Olimpia Poznań, becoming Olimpia-Lechia Gdańsk. Olimpia-Lechia Gdańsk played in the top division, while the continuation of the Lechia Gdańsk team played in the 3rd division, with the Lechia Gdańsk side being used as the team's official second team. By the end of the 1995–96 Ekstraklasa season Lechia-Olimpia Gdańsk finished 16th, and were ultimately relegated. The second team (Lechia Gdańsk) also narrowly miss relegation, finishing just above the relegation places. At the end of the 1995–96 season Lechia–Olympia Gdańsk was renamed as Lechia Gdańsk, promoting the team from the 3rd division to the 2nd. The new Lechia team failed to capitalize on the return to the second division by being relegated to the 3rd division straight away. The 1997–98 season was a better season for Lechia with the team finishing in 3rd place in the III liga.

Before the 1998–99 season Lechia had their 2nd merger within 3 years, this time merging with Polonia Gdańsk to create Lechia-Polonia Gdańsk taking Polonia's place in the 2nd division. This merger lasted 3 years, with the team's fortunes slowly deteriorating, finishing 7th in 1998–99, 14th in 1999–2000, and 19th in the 2000–01 season, and thus suffering another relegation to the 3rd division. In the 2001–02 season Lechia–Polonia competed in the 3rd division, while a newly formed Lechia Gdańsk team was formed in the 6th division. After the 2001–02 season Lechia–Polonia dissolved, resulting newly formed Lechia becoming the continuation of the original club, while Polonia Gdańsk having already reformed in the sixth tier in 1999.

The newly formed independent Lechia Gdańsk team had a lot of initial success, winning the league in its first year in the 6th tier in 2001–02 season. This form continued finishing first in the 2002–03 season in the 5th tier, as well as winning the 2003–04 season in the 4th tier, and also finishing first the season after in the 2004–05 3rd tier. After 4 seasons of being an independent club after failed mergers with Olimpia and Polonia, Lechia found itself back in the second tier of Polish football.

Back in the II liga Lechia finished the 2005–06 in 10th, comfortably above the automatic relegation zone, and clear of the relegation playoffs. With Lechia making more improvements during the 2006–07 season finishing in 5th.

The 2007–08 season was the team's 20th season outside of the top flight, having to come from two failed mergers, and working their way back into the 2nd division. During the season the MOSiR Stadium became a fortress, with Lechia winning 14 of the 17 games at home, losing only once at home, against Odra Opole. Lechia struggled more away from home, winning 6 of their 17 away games. Lechia was helped during the season with goal-scoring contributions from Maciej Rogalski, Paweł Buzała, and Piotr Cetnarowicz, with all three players scoring more than 10 goals over the course of the season. Despite the club's decent away form, it proved by the end of the season that their home form had massively helped Lechia in the league, with Lechia finishing the 2007–08 season as champions, and as a result, secured promotion back to the Ekstraklasa.

For the 2008–09 season Lechia returned to the Ekstraklasa for the first time since being relegated after the 1987–88 Ekstraklasa season. Lechia struggled in their first season of being back in the top flight of Polish football with the team losing 16 of the 30 games that season. They ended the season three points above the relegation zone, and stayed in the league mostly due to their home form (having 7 of their 9 wins that season from their home games). Lechia fared better during the 2009–10 season finishing in eighth, while also enjoying a cup run that took the team to the semi-finals of the 2009–10 Polish Cup losing in the semi-final to eventual cup winners Jagiellonia. In January 2009 the members of Lechia Gdańsk (OSP) signed a document forming Lechia Gdansk S.A. (Spółka Akcyjna = Stock Corporation). It was during this season that Gdansk was chosen to be one of the host cities of the UEFA Euro 2012 championships in Poland and Ukraine, meaning the team would be moving from their current MOSiR Stadium to a new 43,000 capacity stadium in 2011.

In Lechia's 3rd season back in the top flight, it was another season of consolidating their Ekstraklasa status. In the 2010–11 season the team once again finished in 8th place. It was, however, a more positive season that showed progression for the team as a whole. It was the first time since their promotion back to the top league that Lechia had won more games than they had lost, finished with a positive goal difference, and Lechia player Abdou Traoré finished joint runner up for most goals that season. And for the second season in a row Lechia reached the semi-finals of the 2010–11 Polish Cup, before losing 5–0 to Legia over the two legs. This was the last season in which Lechia played at the MOSiR Stadium, the stadium in which Lechia had played all of their home games since their formation in 1945. The last game to be played at the stadium was the final game of the season against Zagłębie Lubin, a game in which Lechia lost 2–1.

The 2011–12 season saw Lechia move into their new stadium, the first game to be played there saw Lechia playing against Cracovia, a game which finished 1–1. Lechia struggled during their first season inside the new and much larger stadium, winning only three of their home games that season. Lechia slumped to a 13th-place finish, in a season where they scored 21 goals in 30 games. In 2012–13 there were more positives for Lechia, again finishing in a mid-table 8th. The team once again struggled at home, winning only three games. With the relegation of Polonia Warsaw (who finished the season in sixth) due to financial issues, Lechia effectively finished seventh, and secured their highest finish since their return to the top flight.

There were major changes made for the 2013–14 Ekstraklasa season with the introduction of a Championship Round (teams who finish 1st–8th) and a Relegation Round (teams who finish 9th–16th). This took the overall games played in a season from 30 to 37. As ever Lechia finished eighth after the 30-game season qualifying for the Championship Round. Lechia finished the first-ever Championship Round in fourth place and just missing out on qualification for the qualifying rounds of the 2014–15 UEFA Europa League due to Zawisza Bydgoszcz winning the 2013–14 Polish Cup. The 4th-place finish meant that Lechia had achieved their highest finish since the 1956 season, in which Lechia finished third.

2014–15 saw Lechia struggling towards the lower end of the table by the time the winter break took place. During the mid-season transfer window Sebastian Mila rejoined the club where he had started his professional career 14 years earlier. The Polish international became Lechia's captain for the remainder of the season, and helped the club to an eighth-placed finish for the regular season. During the Championship Round, Lechia managed to finish in fifth, once again just missing out on qualifying for the Europa League.

2015–16 saw an intent for progression for Lechia. Joining Mila and Łukasik, the Poland internationals who were already at the club, saw the arrivals of Ariel Borysiuk, Sławomir Peszko, Jakub Wawrzyniak, Grzegorz Wojtkowiak, as well as former Serbian international Miloš Krasić. Despite the new players Lechia struggled at the start of the season and hovered above the relegation zone until the winter break. The team managed to reach seventh place by the end of the regular season. During the Championship Round Lechia once again finished fifth, and narrowly missed out on qualification for the Europa League Qualifiers. Grzegorz Kuświk who joined Lechia from Ruch during the summer finished the season with 11 goals, and was one of the top goal scorers that season.

2016–17 saw the improvements that fans had been anticipating. With players such as Haraslín as well as the internationally experienced players who joined the season before had now settled into the club. New arrivals such as twins Marco Paixão and Flávio Paixão, as well as Rafał Wolski arriving from Fiorentina and Dušan Kuciak from Hull City. The regular season saw Lechia winning all but three of their home games, and were top of the table at the end of 10 of the game weeks. Lechia ended the regular season in fourth. In the last home game of the season against Pogoń Lechia celebrated the careers of Piotr Wiśniewski and Mateusz Bąk. Both players had played over 10 years for Lechia, while Lechia was the only professional club Wiśniewski played for. Both players came on as substitutes in the 4–0 win over Pogon, with Wiśniewski scoring the final goal of the game, and Bąk made an important save to keep a clean sheet for the team. Going into the final game of the season Lechia was in fourth place, two points behind Legia who were top, Lechia knew that with a win away to Legia they had a great chance of winning their first-ever Ekstraklasa title. The game finished 0–0, and due to Lech and Jagiellonia drawing with each other, Lechia did not gain any positions and finished fourth with the same points as Lech and Jaga who finished in second and third. For the third season in a row Lechia once again missed out on qualification for the Europa League by a single position, this time due to their main rivals Arka Gdynia getting the place from winning the 2016–17 Polish Cup. Marco Paixão finished the season as the top scorer in the league with 18 goals, an award which was jointly shared with Marcin Robak.

There was much anticipation for the 2017–18 season after having the chance to win the title up until the final game the season before. However, any optimism of a repeat was short-lived. Lechia spent most of the season in the bottom half of the table and finished the regular season in 14th, one place and one point above the relegation zone. This was the first season Lechia had featured in the Relegation Round. Wins against Termalica Nieciecza, Arka Gdynia and Piast Gliwice ensured that Lechia finished the Relegation Round in 13th place, two places and three points above the relegation zone. Marco and Flávio had a huge contribution to Lechia staying up, with 16 goals from Marco and 10 for Flávio. At the end of the season Sebastian Mila retired from football, after having had two spells with Lechia.

Piotr Stokowiec was in place for the final few games of the disappointing 2017–18 season and was in place ready for the 2018–19 Ekstraklasa season. The first game of the 2018-19 season saw Lechia beating Jagiellonia Białystok, with Sławomir Peszko receiving a straight red. After the game Peszko received a three-month ban for a dangerous kick at Arvydas Novikovas. The season started well, with Lechia winning five of their first seven games, while also holding Legia to draw in Warsaw. Lechia's first defeat of the season came away to Wisła Kraków after the international break, before losing a 3–0 lead and drawing 3–3 with Zagłębie Lubin in the game after. After a difficult September, Lechia went on a 13-game unbeaten run, including wins over rivals Arka Gdynia and beating Lech Poznań away in Poznań for the first time in 52 years. The unbeaten run lead to Lechia leading the Ekstraklasa when the league broke up for the winter break. During this time Lechia also went on a cup run beating Wisła Kraków, Resovia Rzeszow and Bruk-Bet Termalica Nieciecza to reach the quarterfinals. After the break Lechia continued their good form losing only 2 of the 11 games after the restart. After losing the final game of the regular season to Cracovia 4–2, they found themselves in the first place due to goal difference, having +3 goals more than Legia Warsaw. Lechia's good fortunes in the cup also continued after the restart, beating Górnik Zabrze in the quarterfinals, Raków Częstochowa in the semifinal, meeting Jagiellonia Białystok in the final. The final was played on 2 May 2019 at the National Stadium in Warsaw. After a close game Flávio Paixão scored for Lechia in the 85th minute, before it was disallowed by the VAR. Artur Sobiech scored the winning goal in the fifth minute of stoppage time, winning the Polish Cup for Lechia, the second time in their history they won the competition. After the cup triumph, the championship group was a disappointment in comparison. After losing only four games in the previous 30, Lechia lost four of the seven championship games. Despite the disappointing end, it was a historic campaign for Lechia after winning the Polish Cup for the second time, and finishing third in the league, their joint highest finish in the league which was last achieved in 1956.

Lechia started the season with the 2019 Polish Super Cup playing against Polish Champions Piast Gliwice. Two goals from Lukáš Haraslín and one from Jarosław Kubicki meant that Lechia were 3-0 up in the final before a late consolation for Piast from Patryk Sokołowski. Lechia won the Polish Super Cup for the second time in their history by winning 3–1. Another challenge for Lechia to face early in the season was playing in a European competition for only the second time in their history. Lechia were to play in the 2019–20 UEFA Europa League, with the team being drawn against Brøndby IF. The first game went well, with Lechia winning 2–1 at home, with goals from Flávio Paixão and Patryk Lipski. The second leg however went Brøndby's way. After finishing the away leg 2–1, with Lechia's goal coming from Flávio Paixão, the game went to extra time. Brøndby scored early in extra time, and with Lechia pushing for an equalizer, scored again late on meaning Lechia lost the tie 5–3 on aggregate. The start of the 2019–20 season proved to be difficult for Lechia, with new signing Žarko Udovičić receiving a four match ban after being sent off in the team's first game of the season against ŁKS Łódź. Lechia went on to only win one of their first six games, which was against Wisła Płock. After the difficult start Lechia then went on a five match winning run which put them top of the league after beating Legia Warsaw away 2–1. After their winning run was ended by Zagłębie Lubin, the team had the Tricity Derby the following game. After goals from Artur Sobiech and Flávio Paixão (this being Paixão's seventh goal against Arka, making him the outright highest scorer in the fixture) Lechia lost a 2–0 lead and finished the game 2–2, with Udovičić again being sent off, this time receiving a two-month ban. After the game against Arka, Lechia failed to win any of the next three games, losing two, placing the team in 9th place at the mid-way point of the regular season. For the start of the second round of fixtures Lechia beat ŁKS Łódź 3–1, with Flávio Paixão scoring two goals. These two goals put Paixão on 68 goals in the Ekstraklasa, overtaking Miroslav Radović as the highest scoring foreigner in the top league of Poland. Lechia went on to win the next two games while managing to keep clean sheets in both games. The 3 match winning run was ended after a 3–0 defeat against Jagiellonia Białystok. It was announced a few days after the game, on 17 December, that the players and staff had not been played by the club since September and had failed to pay the players their bonuses for winning the Polish Cup in May. Due to the players having not been paid for months they would have been legally be able to apply for a termination of their contract, and leading to the possibility of many important players leaving during the next transfer window. After the finances had been resolved, Lechia lost the final game of the autumn round 3-0 going into the winter break in 7th. To help with the club's future financial situation key players on high wagers were told they could leave during the winter break. Key players that left included; Lukáš Haraslín, Artur Sobiech, Daniel Łukasik, Rafał Wolski and Sławomir Peszko with Błażej Augustyn training with the Lechia II team until arrangements could be made. Although key players were missing and there being a greater emphasis on playing the youth players in the first game back after the winter break, the team started the second half of the season drawing 2–2 with a Championship chasing Śląsk Wrocław team. During the game it was clear to see the club's current situation with their finances with the entire bench being made up of teenagers from the U23's team. Lechia won the following game 1–0 against Piast with Kacper Urbański starting the game, becoming the youngest ever Lechia player to start a competitive game, and the youngest ever player to start a game in the Ekstraklasa. On 10 March it was announced that all games would be played behind closed doors due to the coronavirus pandemic. After the announcement Polish football would be played without fans present, Lechia went on to beat Piast Gliwice 2–1 in an empty stadium in the Polish Cup to reach the semi-finals, leaving only 2 wins to retain the cup. Announcements were made over the following days and weeks, with the Ekstraklasa, I liga and Polish Cup fixtures all being suspended until 26 April at the earliest. At the time of the league's suspension Lechia were in 7th place with 4 games left to play in the regular season. After a difficult restart to the season Lechia went on a run to climb the table, including a 4–3 win over rivals Arka Gdynia. This run coincided with the meeting of Lech Poznań in the Polish Cup semi-final, against whom Lechia beat 4–3 in penalties after the game finished 1–1. This led Lechia into their second Polish Cup final in successive years. Lechia finished the season in 4th place and played Cracovia in the Polish Cup final, losing the final 3–2 after the game went into extra-time.

Lechia went into the 2020–21 season celebrating their 75th anniversary, but with the fans and team knowing they had lost some key players from previous seasons. Filip Mladenović joined rivals Legia Warsaw while Lukáš Haraslín made the permanent move to U.S. Sassuolo. Lechia struggled at the start of the season, losing two of their first three games, before finding some form and moving to a high of 4th place. The effects of the coronavirus were again felt by the team, with the match against Wisła Kraków being postponed due to an outbreak in the Wisła team. Lechia eventually struggled with a Covid outbreak of their own, with Jaroslav Mihalík being the first confirmed case in the club on 10 October, getting the virus while on international duty. In early November the club had an outbreak affecting 13 players and 7 members of the coaching staff. After a month with no games due to the team's outbreak the Lechia team returned to play Śląsk Wrocław, winning the game 3–2. After this initial success after the team's isolation, Lechia lost the following four games without scoring a goal. Going into the final game before the winter break the team found themselves in the bottom half of the table, but a 3–0 win over Cracovia helped them to rise up to 8th. After the winter break Lechia's poor form returned with defeats to Jagiellonia in the league and Puszcza Niepołomice in the Polish Cup, with some fans questioning the role of Stokowiec as the team's manager. After a poor run of results which saw 6 defeats in 7 games, Lechia picked up form and gained some momentum in the league, winning 5 of the next 8 games, losing only one, and mounting a threat to the top three places in the league. After this run Lechia's form once again dropped, winning only 6 points from the final 7 games of the season. The team went into the final game of the season knowing that a win would be enough to secure European football for the following season, but a defeat to Jagiellonia on the final day of the season saw the side slump to a disappointing 7th-place finish.

The 2021–22 season saw changes in the league structure, increasing the teams from 16 to 18 and scrapping the championship and relegation leagues at the end of the season, seeing all teams playing 34 league games a season instead of the previous 37. The 2021–22 season started relatively well for Lechia losing only one of their first six games and securing 9 points in the process. Lechia dropped points against Radomiak Radom in their sixth game of the season after having been 2–0 up to draw the game 2–2. While the season looked more promising, and they play from the squad looked better than the previous season, this kind of collapse in Lechia games was becoming too common under Stokowiec's reign. Shortly after the game with Radomiak it was announced that Piotr Stokowiec had officially left the club, Stokowiec being Lechia's second longest serving manager in the club's history. On 1 September 2021 it was announced that the Pogoń Szczecin assistant manager Tomasz Kaczmarek was to become the new Lechia manager. Lechia under Kaczmarek initially performed well in the league, going on a nine-game unbeaten run in the league under the manager, a run of 10 games in total with Stokowiec's last game in charge being included. During this unbeaten run of games, Lechia convincingly beat teams such as their wins against Górnik Łęczna and the current Polish champions, Legia Warsaw. This good form saw Lechia closing in on the leaders Lech, and going on to fight for a few weeks with Raków for the second and third places. The impressive run came to a disappointing end with a 5–1 defeat to Pomeranian rivals Pogoń which saw Lechia's run of form drastically change, going on to lose 3 of the next 4 games, and being in 5th place in the league as the Ekstraklasa stopped for the winter break. After the break Lechia's inconsistent form continued, seeing a convincing win against Śląsk, before being convincingly beaten against Cracovia. Lechia's third game of the league's return was against the league leaders Lech Poznań, with the club needing a positive result to keep up the pace with the teams in the top 3 places. Despite Lech being the dominant team for much of the game, a late goal from 17 year old Filip Koperski secured a 1–0 win against their league rivals, and keeping themselves in touching distance of a top 3 finish. The win against Lech proved to be a blip, with the club failing to win any of the next three games including losing against Radomiak Radom who were also trying to reach the top 3, and only drawing with relegation candidates Wisła Kraków. Financial struggles around the club were once again raised, and could be seen as a reason for the club's poor performance, however these concerns were soon quashed and the situation was not as bad as first feared. Despite these concerns, Lechias form improved, with the club going on to win 5 of the next 7 games, and with Raków Częstochowa winning the Polish Cup, 4th place would be good enough for Lechia to secure European football. One game of note in this run was against Warta Poznań, with Flávio Paixão scoring both goals in a 2–0 win, and in the process scoring Lechia's 1000th Ekstraklasa goal, and becoming the first foreign player to score 100 goals in the Ekstraklasa. The penultimate game of the season saw them face off against Pogoń Szczecin knowing that a draw would secure 4th place in the league and the chance to play in Europe. Despite both teams starting the game strongly the contest fizzled out to a 0–0 draw. This was enough for Lechia to secure their place in the following seasons Europa Conference League, only their third time of playing European football in their history.

The following 2022–23 season was very unsuccessful for Lechia. In the Conference League qualifiers, after beating Akademija Pandev in the first round, they got eliminated from European football by Rapid in the following round. They ended their Polish Cup journey in the round of 16, losing the penalty shootout to Legia, who went on to win the competition. Most notably however, the White-Greens were relegated after losing at home to Zagłębie Lubin in the 31st matchday on 6 May 2023, ending their fifteen-year stint in the top flight.

Following relegation, many of the key players left the club, such as Łukasz Zwoliński, Jarosław Kubicki, Michał Nalepa and Flávio Paixão, among others. Led by their new manager Szymon Grabowski, Lechia contested the first round of the 2023–24 I liga against Chrobry Głogów with a matchday squad consisting of 8 youth players with no prior senior team playing experience. The club was also facing financial and organizational issues, including delayed staff payments and having to use placeholder kits in the early stages of the season. Following change of ownership in August, the arrival of foreign players such as Ivan Zhelizko, Maksym Khlan, Rifet Kapić and the record signing of Camilo Mena, Lechia found their footing in the second division. On 11 May 2024, they were promoted back to Ekstraklasa at their first attempt, after a 4–3 win over Wisła Kraków. They later became I liga champions on 19 May, following a 2–1 Tricity Derby win over Arka Gdynia.
