In the following season, after many troubles, Legia finally played in the First League with a very strong squad that was expected to fight for a return to the national elite. Unfortunately, Legia performed below expectations - they advanced to the playoffs from the eighth place and lost 0-3 to Turów Zgorzelec in the first round of the playoffs. Warsaw continued to struggle with financial problems, resulting in the team not registering for the First League. Legia spent the 2003-04 season in the Second League, which was the third tier of national championship, and even at this level had to fight against relegation.
