Dereck Chisora has warned David Haye that he will be at his "craziest" when the two meet in their controversial bout on Saturday.

Chisora and Haye will fight at Upton Park in a grudge match that started when Haye interrupted the post-fight press conference between Chisora and Vitali Klitschko.

The two boxers came to blows, causing Chisora to be banned by the British Boxing Board of Control.

However, the Luxembourg Board of Control sanctioned the bout, and Chisora believes that it is going to be a great fight.

"I'm going to be the craziest I've been when I come into the ring," Chisora said.

"Everything has gone well for me, I have no injuries and it's going to be a great fight."

Chisora has been widely criticised for his behaviour during recent fights, such as slapping Vitali in a pre-fight press conference and spitting water at Vitali's brother Wladimir immediately before the fight.
