David Haye will attempt to unify the heavyweight division once more this year after he takes care of Dereck Chisora - a man he branded "chubby" and an "idiot" yesterday.
Haye yesterday announced that he will come out of retirement to fight fellow Londoner Chisora in a controversial showdown at West Ham's ground on 14 July.
The 31-year-old last fought in July 2011 when he lost to WBA, IBF and WBO heavyweight champion Wladimir Klitschko - a defeat he blamed partly on a broken little toe.
Haye has long coveted a rematch with Wladimir or a fight against his older brother Vitali, who holds the WBC belt, and hopes to take on one of the Ukrainians later this year.
"That fight will happen, but in September at the earliest," Haye said.
"If it could have been agreed already I wouldn't be fighting Chisora.
"I have always been looking for that fight against the Klitschkos. That's the one thing I've got left to do - to unify the titles."
Haye and Chisora caused outrage when they brawled after the latter's heavyweight title shot against Vitali Klitschko in Munich on 18 February.
The scrap, and Chisora's decision to slap Vitali and spit water at his brother in the run-up to the fight, left many claiming boxing had hit a new low, and the Zimbabwe-born fighter had his licence removed by the British Boxing Board of Control (BBBC).
That means organisers have had to ask the Luxembourg boxing federation to sanction the Haye-Chisora fight - a decision which Wladimir finds ridiculous.
"It's a freak show under freak rules," Klitschko told BBC Radio 5 live. "It's a spit in the face of the British Boxing Board of Control. To get a licence for this man (Chisora) is disgraceful for the sport.
"How can you have such an event featuring a man who has shown his behaviour to the world, especially considering what he did at the press conference, where he threatened Haye. It's something that isn't good for the fans and sport.
"How's it possible that this is happening on British soil?"
The BBBC are also unhappy with the fight going ahead.
General secretary Robert Smith said: "We're having a meeting (on Wednesday) and we'll put word out then.
"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."
Chisora's manager Frank Warren insists he is not undermining the British board, however.
Warren said: "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."
It was clear that the three months that have passed since the Haye-Chisora fracas have not mellowed either fighter's feelings towards each other at the announcement of their fight yesterday.
Haye yesterday claimed Chisora was an "idiot" who has a "few screws loose", while his opponent retorted, over the seven-foot steel fence which separated the two: "I don't like him. "I will do the ****."
Haye vowed never to fight professionally again after his 31st birthday passed last October, but he carried on training in his gym in central London and has promised he will be physically prepared to take on his 28-year-old opponent in July.
"I am in shape. I am a healthy person unlike Dereck," Haye added.
"He is chubby. He eats fast food and drinks alcohol a lot. That's his thing.
"It obviously doesn't work for him because he has lost his last three title fights."
