Mateusz Legierski and Gökhan Aksu are slated to face off for the lightweight championship at OKTAGON 90, with the event scheduled to take place at Berlin’s Uber Arena on Saturday, June 20. This highly anticipated bout was initially planned for Poland, but an injury to Legierski forced a postponement. The reigning champion has now recovered and is prepared to make his first title defense.
Legierski Aims to Cement Reign, Aksu Seeks Title Glory
Mateusz Legierski recaptured the lightweight title in November 2025, defeating Attila Korkmaz over five rounds in Munich. This victory re-established him as the top contender in the division. Legierski boasts an impressive record within OKTAGON, with previous wins against Karol Ryšavý, Matouš Kohout, and Akonne Wanliss. He is recognized as a former champion who has yet to be defeated by any opponent in the OKTAGON cage. His path back to the top has been challenging, as a severe back injury sidelined him for over a year, casting doubt on his ability to return.
Gökhan Aksu has rapidly gained momentum since his arrival in OKTAGON in late 2024, and his recent string of victories has propelled him into title contention. He secured a submission win against Jan Malach, achieved a first-round TKO against Ognjen Dimić, and earned his championship opportunity with a knockout victory over Denis Frimpong following a heated rivalry. Throughout his professional career, Aksu has been known for his quick finishes and remains undefeated in his last six fights, having stopped every opponent he has defeated within the distance.
OKTAGON 90 is being promoted as a significant event, marking the organization’s debut in Berlin and taking place at the renowned Uber Arena. The card will also feature a heavyweight title clash between Will Fleury and Kasim Aras, alongside other compelling matchups such as Alina Dalaslan vs. Djulia Ariana and Denis Frimpong vs. Niko Samsonidse. Attila Korkmaz is also scheduled to compete against Dawid Śmiełowski, contributing to a strong undercard supporting the main title fights.
This fight presents Legierski with an opportunity to re-establish his championship dominance after his injury layoff, while Aksu has the chance to seize a high-profile victory that could significantly alter the division’s landscape. The choice of Berlin, one of Europe’s largest indoor arenas, underscores OKTAGON’s commitment to launching its presence in the German capital. For Legierski, the objective is clear: defend his belt and continue his comeback narrative. For Aksu, it’s a pivotal moment to translate his impressive unbeaten streak into a championship win on a grand stage, potentially in front of a challenging crowd.
