Boxing: Dereck Chisora predicts heavy defeat for David Haye Dereck Chisora is adamant his personal pride will not allow him to lose to David Haye and warned his bitter rival that the defeat he is predicting will be the worst of his career. Haye's last fight ended in a unanimous decision defeat to WBA, WBO, IBF and IBO world heavyweight champion Wladimir Klitschko but before that, his only other loss came at cruiserweight when Carl Thompson brutally stopped him in five rounds in 2004 and it is this Chisora is looking to surpass. "There's too much pride on the line," said Chisora, who finally fights Haye at Upton Park on 14 July. There's no way I'm going to lose to Haye. I'm going to break him down mentally and physically, he's all mouth and he now knows that he's in a real fight against me. What's he going to do when he lands his best punches and they have no effect and I'm still in his face throwing punches? Haye's going to wish he was in the ring with Carl Thompson again, that was mild compared to what I'm going to be dishing out to him. It's going to be like a bad dream coming back to haunt him, I'll leave him hanging on the ropes just like Thompson did. I'll be taking Haye out of the game, this will be his last fight in boxing and he can forgot about fighting any Klitschko again. Wladimir played with him for twelve rounds, the difference is I'll be punishing him for twelve rounds and giving him the worst beating he's had. I'll destroy him. He'll need more than one of his Hayemakers to stop me coming at him at night.
