Derek Chisora has issued a bold warning to Daniel Dubois ahead of his highly anticipated rematch with Oleksandr Usyk, claiming the British boxer must transform into a 'crazy demon' to stand a chance against the Ukrainian champion.

Chisora, who faced Usyk in a grueling bout in 2020, shared insights into the mental toughness of the reigning heavyweight king. He recalled a phone call with Usyk during which the Ukrainian remained calm despite the sound of missiles exploding nearby, a testament to his unshakable resolve. "He was in his front room while his family was in the bunker, just listening to missiles fly over," Chisora revealed. "This is the kind of man Daniel is up against."

Usyk, a former Olympic gold medalist and undisputed cruiserweight champion, has proven his dominance in the heavyweight division with victories over top-tier opponents like Anthony Joshua and Tyson Fury. Chisora emphasized that Dubois must adopt a fearless, almost unhinged approach to disrupt Usyk's composure. "The only way to beat Usyk is to find someone crazier than him," Chisora stated. "Daniel has to walk into Wembley Stadium and become a demon. No doubts, just go for it."

Dubois, 27, is seeking redemption after his 2023 loss to Usyk, where a controversial low-blow ruling overshadowed his performance. Since then, he has secured impressive wins over Jarrell Miller, Filip Hrgovic, and Anthony Joshua, showcasing his growth as a fighter. However, Chisora cautioned that overcoming Usyk’s technical brilliance and mental fortitude will require more than just physical preparation. "These Europeans are different from us English," Chisora noted. "They’re real men, and Usyk is a man of God. He’s got it all perfect."

The rematch, set to take place at Wembley Stadium, promises to be a thrilling encounter. Dubois will need to channel the 'crazy demon' mentality Chisora described if he hopes to dethrone the Ukrainian legend and claim the undisputed heavyweight crown.
