David Haye vowed to inflict a "slow, concussive beating" on Dereck Chisora after their controversial grudge match was confirmed yesterday.

Frank Warren, Chisora's manager, announced yesterday afternoon that West Ham United's Upton Park ground would host a fight between the two British heavyweights on July 14.

The pair sparked outrage when they brawled in the press conference room following Chisora's points defeat by Vital Klitschko, the World Boxing Council heavyweight champion, in February.

At a heated press conference at Upton Park yesterday – the Haye and Chisora camps were separated by a 7ft steel fence – the two men exchanged insults and Haye vowed to beat Chisora in July.

"He is the ideal opponent for me," Haye said. "I am so glad he has got a good chin because, if he didn't, he would be blasted out in the first round. This means I will give him a nice, slow, concussive beating. I tried to knock him out in Munich and this is the opportunity to shut him up."

Chisora, flanked by eight burly security guards, angrily retorted: "I don't like him. David, you need to get style. Your corn rows are out of fashion. That was a lucky shot he hit me with in Munich.

"David, you are winning 1-0 but, come July, I am coming to whoop your ass. Your talk is cheap. You always talk but you don't deliver in the ring."

The two men exchanged another barb, revealing they had seen each other in London recently. Chisora said: "I saw David a couple of weeks ago and he pulled a knife." Haye responded: "I was eating a steak; it was in a restaurant."

The fight has had to be sanctioned by the Luxembourg Boxing Federation after the British Boxing Board of Control withdrew Chisora's licence following his antics in Munich.

Haye does not have a British licence after he handed it in following his last fight in 2011: his defeat by Wladimir Klitschko.

Warren insisted that he was not undermining the BBBC by going to Luxembourg for the fight's licence. "This is not the end of British boxing," Warren said. "I believe it will be a sell- out. There are far, far worse things happening in sport than what's happening here.

"No charges have been made against Haye or Dereck for what happened in Munich. The hearing was put back to July so Dereck will have effectively been out of the ring for six months and that equates, if he was a footballer, to being out of action for 24 matches," Warren added. "He has lost half of his purse in sanctions and costs since the Klitschko fight. He has no qualifications, the next thing for him to do would be to sign on.

"He is not banned from boxing. The fight has been licenced by the governing body in Luxembourg, which has the same standards as the BBBC. 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."

Robert Smith, the BBBC's general secretary, made it clear they were furious with another board sanctioning the fight.

"We're obviously not happy about it as it's not what we feel should happen," said Smith. "Another country has come into our jurisdiction and over-ruled us."
