Two-division undisputed champion Oleksandr Usyk has named the toughest opponent he has faced in his career.
"I think it’s Derek Chisora, my friend. Hey, Derek, I’m keeping an eye on you.
Derek is a scary guy, very tough. He’s brutal. I don’t know, he’s just solid. It was a hard fight, that’s it," Usyk said.
Usyk and Chisora fought in 2020, with Usyk winning by unanimous decision. Now, Chisora has been calling for a rematch, publicly challenging Usyk to run it back.
