Aruna Quadri

Aruna entered the Men's Singles event at the 2016 Summer Olympics as seed number 27. In the first round, he played and defeated Slovakian player Wang Yang (4-1). In the second round, Aruna played the number 5 seed Chuang Chih-yuan. Chuang grew repeatedly frustrated as the match went on, uncharacteristically missing his signature forehand attacks and was at a loss against Aruna's unorthodox style. Aruna defeated Chuang in arguably the tournament's biggest upset without losing a single set (4-0). Aruna faced world-renowned German player Timo Boll in the third round. Aruna defeated Boll (4-2), earning him a spot in the Quarter Finals. In the Quarter Finals, Aruna faced the tournament's number one seed, a Chinese player Ma Long. Long overwhelmed Aruna with fast-paced, looping attacks. The match proved entertaining as Aruna was forced to play defensively and back from the table, providing memorable rallies. Ultimately, Long swept Aruna to move onto the Semis (0-4).

Aruna's run in the Singles event of the 2016 Olympic games was quite easily the most remarkable achievement of his career at the world level. Having upset number 5 seed, a semi-finalist in the previous Olympics, and four-time World Tour Champion as well as ten-time runner-up, Aruna also upset a European legend in Boll. Although eventual winner Ma Long swept Aruna, Long also swept the Gold medal match. He was the only African competitor to reach the fourth round.

In the team event, Aruna competed alongside Segun Toriola and Bode Abiodun. The team was seeded against Team China in the first round, in which Aruna played and was defeated by Ma Long (1-3). The team lost all three matches to China and was eliminated (0-3).

Aruna competed in the 2017 ITTF African Cup, qualifying for the quarter-finals, where he defeated Algeria's Naim Karali (4-1). In the semi-finals, Aruna defeated Egyptian player Mohamed El-beiali (4-3), qualifying for the finals. In the Finals, Aruna played and defeated long-time rival Omar Assar in a close match (4-3). Aruna won the event and became the 2017 African Cup Champion.

Aruna competed in the World Championships, seeded as number 30. He defeated Chilean player Gustavo Gómez (4-0). Danish player and number 34 seed, Jonathan Groth, defeated him in the second round.

Aruna competed in the 2018 ITTF African Cup, placing first in group 2, allowing him to qualify for the Quarterfinals. In the Quarterfinals, Aruna defeated Derek Abrefa (4-0). In the Semi-Finals, he defeated Ahmed Saleh (4-1), allowing him to advance to the finals of the African Cup.

The 2018 African Cup Finals featured two of the only African players within the top 50 of the ITTF World Rankings, 2015 and 2016 Champion Omar Assar against reigning 2017 Champion Aruna. Assar, seeking retribution for last year's defeat, played a very aggressive attacking game, winning the first two games with close scores (10-12 and 8-11). The third game entailed a dominant performance from Aruna, attacking Assar relentlessly (11-3). In the fourth game, Assar targeted Aruna's deep forehand, forcing Aruna to play much more uncomfortably than in the previous games. However, Assar lost some points in an earnest attempt to end rallies early. Assar took the game (11-13). Aruna won the next two games (11-9 and 11–6), tying the two up 3-3. In the final game, Assar took an early lead of 3–7, following a few well-placed shots and missed attacks from Aruna. Aruna rallied back into an 8–10 deficit before losing the final point on a failed forehand loop (3-4). The loss placed Aruna Second in the 2018 African Cup.

The crowd has been particularly invested in the match between these two rivals. The rivalry extends beyond the two world-class players into the feud for African Table Tennis supremacy between Egypt and Nigeria, having both produced some of the continent's strongest players over the last decade (Segun Toriola, Monday Merotohun, Olufunke Oshonaike, Dina Meshref, El-sayed Lashin, etc.). This emotion is highlighted in the match's aftermath as Assar celebrated to the cheers of his fans on the top of the table.
