Haye: This is personal
David Haye claims Dereck Chisora has got "a few screws loose" after agreeing to a very "personal" and controversial grudge match.
After a week of speculation, it was confirmed that Haye and Chisora will fight at Upton Park on July 14.
The pair sparked outrage by brawling after Chisora's world heavyweight title defeat to Vitali Klitschko in Munich this February.
Glass bottles, tripods and punches flew in the scrap, and it was clear that there is still a deep-rooted animosity between the pair when they met at a press conference to promote their fight at West Ham's ground.
Chisora and Haye traded insults over a seven-foot steel fence that separated them, and at least a dozen security guards were on hand to prevent any repeat of the Munich brawl.
"This is definitely personal," said Haye after the main press conference ended.
"We genuinely don't like each other. He has threatened to break my jaw, he has threatened to slap me.
"This fight is about eradicating boxing of an idiot. I am so glad he has got a good chin because if he didn't he would be blasted out in the first round. I will give him a nice, slow, concussive beating."
Chisora's antics before the February 18 fight in Germany also caused outrage, with the Londoner slapping Vitali at the weigh-in and spitting water over his brother Wladimir prior to the bout.
Chisora was stripped of his licence, meaning organisers had to have his next fight sanctioned by the Luxembourg boxing federation.
Chisora has a history of troubles both inside and out of the ring. He has convictions for assaulting his girlfriend, carrying an offensive weapon and assaulting a police officer.
The 28-year-old has also kissed an opponent during a weigh-in and bit another in the ring, prompting Haye to question his state of mind.
"I truly believe he has a screw loose, a few screws loose actually," said Haye, who is coming out of retirement for the fight following his points defeat to Wladimir last July.
"Dereck does some really strange things. I have seen him get hold of a guy and kiss him, I have seen him push another guy in the face at the weigh-in and look at his criminal record - bashing up his missus, assaulting police officers, carrying offensive weapons..."
For that reason, Haye insists there will be separate weigh-ins for both fighters - a scenario that was played out when Mike Tyson fought Lennox Lewis at the height of their rivalry.
"The head-to-head weigh-in is off the cards," the 31-year-old added.
"It's not happening because it will kick off.
"At no stage do I want to be in this guy's personal space because we have done that before and it didn't end up nicely.
"If there wasn't a fence there today I know for a fact that he would have tried to do something.
"He's just the most bizarre person. He was talking mad things through the fence.
"He was asking where I got my suit from, what I am doing on Sunday. The guy is mental. He's gone in the head."
Chisora, wearing the same Union Jack face mask he donned when slapping Klitschko, hit back at his opponent.
"I will do the c***. He doesn't wind me up," Chisora said.
"I apologised for saying I would shoot him (in Munich). I never want to take a father from their kids but I do want to whoop his a**. I'm not scared of him."
The British Boxing Board of Control (BBBC) today criticised the decision to stage the fight, with general secretary Robert Smith saying: "We're obviously not happy about it as it's not what we feel should happen.
"Another country has come into our jurisdiction and overruled us."
Warren hit back at critics of the fight, which will be shown live on BoxNation, saying: "There are far worse things happening in sport than what's happening here.
"Dereck appealed (against the BBBC's decision to strip him of his licence), but the hearing was put back to July.
"The fight has been licensed by the governing body in Luxembourg, which has the same standards as the British board.
"It is the biggest fight of the year and the fact of the matter is that the fight is legal, lawful and will go ahead."
