David Haye has claimed that Dereck Chisora will be facing the "best ever Hayemaker" when the two fighters meet at Upton Park on Saturday.
Haye and Chisora will go toe-to-toe in a highly controversial grudge match after the two came to blows in the press conference in February.
Chisora has warned Haye that he will be at his "craziest", but the former WBA heavyweight champion believes that he will knock Chisora out quickly, labelling the controversial fighter "stupid".
"Dereck's getting knocked out quick. The harder he comes the quicker he gets KO'd. My training has been good. I'm healthy, fit and fast," said Haye.
"This training camp has been one of the first I've been able to do everything we planned because nothing has broken down. It's a situation I've never been in before and I can feel the difference.
"My sparring partners have felt the difference as well. Unfortunately for Dereck he's fighting the best ever Hayemaker."
Haye is coming out of retirement to participate in the fight and has won 25 of his previous 27 bouts, all but two of which have come via knockout.
