The highly anticipated lightweight championship bout between Mateusz Legierski and Gökhan Aksu is confirmed for OKTAGON 90, set to take place at Berlin’s prestigious Uber Arena on Saturday, June 20. This clash was initially slated for Poland but was postponed due to an injury sustained by Legierski. Now fully recovered, the champion is ready to make his first defense.
Legierski’s Championship Reign and Road to Recovery
Mateusz Legierski regained the lightweight title in November 2025 with a dominant five-round victory over Attila Korkmaz in Munich, solidifying his position at the top of the division. Legierski boasts an impressive OKTAGON record, with previous wins against formidable opponents like Karol Ryšavý, Matouš Kohout, and Akonne Wanliss. He is recognized as a former champion who has never been defeated within the OKTAGON cage. His journey back to the top has been challenging, marked by a severe back injury that sidelined him for over a year and raised doubts about his potential return to competition.
Aksu’s Rapid Ascent to Title Contention
Gökhan Aksu has made a significant impact since his arrival in OKTAGON in late 2024, rapidly climbing the ranks and earning his shot at the title. His recent string of victories includes a submission win against Jan Malach, a first-round knockout of Ognjen Dimić, and a decisive knockout victory over Denis Frimpong, following a heated rivalry. Throughout his professional career, Aksu has been known for his explosive finishes and remains undefeated in his last six fights, having ended every bout he won within the distance.
OKTAGON 90: A Landmark Event in Berlin
OKTAGON 90 is poised to be a historic event, marking the promotion’s debut in Berlin with a spectacular card at the renowned Uber Arena. Headlining the event will be a heavyweight title clash between Will Fleury and Kasim Aras. The night will also feature exciting matchups such as Alina Dalaslan vs. Djulia Ariana and Denis Frimpong vs. Niko Samsonidse. Furthermore, Attila Korkmaz is scheduled to face Dawid Śmiełowski, rounding out a strong undercard for the championship fights.
This fight presents Legierski with the opportunity to re-establish his championship dominance after his injury layoff, while Aksu aims to leverage his impressive winning streak into a title victory. The choice of Berlin and the iconic Uber Arena underscores OKTAGON’s ambition to make a significant impact in Germany. For Legierski, the objective is clear: defend his title and continue his comeback narrative. Aksu, on the other hand, seeks to crown his undefeated run with a championship belt in front of a fervent crowd.
