Haye ready to be boxing heavyweight

New WBA and WBC cruiserweight champion David Haye claimed he was "95 per cent sure" he would now make the step up to the heavyweight division following his superb victory over Jean-Marc Mormeck in Paris.

Haye, 27, defeated Mormeck on a technical knockout after flooring his French opponent with a lethal right upper cut-right hook combination in the seventh round.

Haye admitted it had been hard to make the weight for the fight as he was a "natural heavyweight", and revealed he was likely to relinquish his new titles for a shot at the big time.

On the prospect of leaving the cruiserweight category, Haye said: "It's a very strong possibility. I'm 95 per cent sure I will.

"These are cruiserweight titles, but I am heavyweight. It's my natural weight. I have trained for 17 weeks to get to 90 kilos and it is not healthy. I am skin and bones."

Haye's victory, which came in Mormeck's back yard, was all the more impressive given the fact he was knocked to the canvass in the fourth round.

At the time, the Bermondsey fighter looked in trouble but he recovered to stun the passionate crowd at the Palais des Sport Marcel-Cerdan on the outskirts of the French capital.

"That was a good shot," Haye said of Mormeck's blow that sent him tumbling.

"He hit me on the temple. But it happens in boxing and we know he is a great fighter.

"When I was down, I said to myself, 'this is all part of it - if you are going to be champion, you have to get up and get on with it'.

"That's what I did. It was meant to be."

Haye did not dismiss the possibility of returning to the venue for a rematch with the 35-year-old Mormeck.

"It's a one-off fight, I don't have to come back. But I will fight who the fans want me to fight. If people want me to come back, I will. I'm in boxing for the fans. If they want it, I'll come back.

"I came into Mormeck's home town and I will go anywhere - America, Russia, anywhere.

"I feel I am the best fighter in world, even at heavyweight."

Mormeck vowed to fight on after the defeat to Haye.

"I still have the desire, even if on this particular night I couldn't do it. I still have a great future.

"Congratulations to David. I tried but I lost - that's boxing. I can't explain what happened. When I realised I was hurt, I couldn't get up. Even with the greatest will in the world, I couldn't carry on.

"I want to acknowledge the talent of David. But it's not my last fight. I chose to fight David and I hope to fight him again."
