Imagine being undefeated in 24 professional fights, having conquered two weight divisions, and being hailed as one of the greatest boxers of your era. You’d think picking your toughest opponent would be a no-brainer, right? Wrong. Oleksandr Usyk, the Ukrainian boxing maestro, recently dropped a bombshell that has the boxing world scratching its head. When asked who his most challenging foe has been, Usyk didn’t hesitate: Derek Chisora, a name that might surprise even the most seasoned fans. But here’s where it gets controversial—Usyk didn’t just call Chisora tough; he labeled him a ‘terrible guy,’ not in character, but in sheer difficulty to face in the ring.
Usyk’s resume is nothing short of legendary. An Olympic gold medalist, he dominated the cruiserweight division, outclassing the likes of Mairis Briedis, Murat Gassiev, and Michael Hunter. Briedis, in particular, pushed Usyk to his limits in their 2018 clash, with many believing the Latvian had done enough to secure the win. Yet, Usyk emerged victorious, extending his unbeaten streak before making the leap to heavyweight—a division often dubbed the ‘land of the giants.’ There, he cemented his legacy with career-defining wins over Tyson Fury, Anthony Joshua, and Daniel Dubois, each defeated twice, solidifying his status as the heavyweight king of his era.
And yet, it was Chisora, a fighter Usyk faced in 2020, who he claims gave him his toughest night in the ring. While Usyk secured a unanimous decision victory, Chisora’s relentless pressure and physicality provided a grueling introduction to heavyweight boxing. ‘Derek is a terrible guy, terribly tough,’ Usyk told talkSPORT. ‘It’s just hard [fighting] Derek. He was just very difficult.’ This admission, made again in February 2025, has sparked debate among fans and analysts alike. Was Chisora truly Usyk’s toughest test, or is this a nod to the unique challenges Chisora presented—his unrelenting style, his ability to absorb punishment, and his sheer determination?
But here’s the part most people miss: While Usyk’s technical brilliance has often made him look invincible, Chisora’s fight exposed a rare vulnerability—the physical toll of facing a heavyweight with such relentless aggression. It’s a reminder that even the greatest champions can be pushed to their limits by fighters who, on paper, might seem less technically gifted. And this raises a thought-provoking question: Is boxing’s greatest challenge always found in the most skilled opponents, or can it lie in the raw, unforgiving nature of a fighter like Chisora?
What do you think? Did Usyk get it right, or is there another opponent who deserves the title of his toughest challenge? Let’s hear your thoughts in the comments—this is one debate that’s far from over.
