Dillian Whyte is scratching his head at the unexpected business partnership between former British rivals Dereck Chisora and David Haye.

Whyte, who a close twelve round split decision over Chisora in December 2016, will face him for a second time on December 22 at The O2 in London.

Back in 2012, Haye knocked out Chisora in five rounds.

Their fight came together after the two boxers were involved in an infamous press conference brawl in Germany. Haye broke a bottle over Chisora's head, Haye's ex-trainer Adam Booth had a bad laceration on his head after being struck with an object, and plenty of punches were thrown all around.

Whyte is not convinced that Haye and Chisora will be capable of co-existing with each other.

"I think the wheels will definitely fall off because Dereck is a mad man. You have to know how to deal with Dereck and David is a narcissist and an egotistical maniac and it's hard to work with someone like that. Dereck is very proud and stubborn and forceful but they're similar in many ways and David is probably going to think 'I don't need this, I got you the fight and I got my 25 percent," Whyte told Daily Mail.

"If David sticks it out then its a real achievement; it's more of an achievement for David than for Dereck. Dereck is saying he's doing this and doing that, that he's sleeping now, its nonsense. You're a grown man, David Haye says start sleeping and you start sleeping?

"Because David Haye glassed him at that brawl, and broke [trainer] Don Charles' jaw and bashed him up in the ring. Maybe he thinks "this guy bashed me up in and out of the ring and so he knows more than Don Charles. Maybe he doesn't think Don Charles is capable enough to get him to this level and David's beaten him."
