No age concern for Holyfield

Evander Holyfield admits he could fight on past the age of 50 as he bids to become the undisputed heavyweight champion of the world.

The American will have turned 48 by the time he next steps into the ring to defend his WBF belt against compatriot Sherman Williams in November.

However 'The Real Deal' is already looking ahead to possible showdowns with current champions David Haye, who holds the WBA belt, and the Klitschkos, Vitali the WBC champion and Wladimir the IBF/WBO holder.

"My goal is to be undisputed heavyweight champion of the world. I'm close to it," he told Sky Sports News HD.

"With David Haye and the two Kltischko brothers... when I get that opportunity to be the undisputed champion of the world I can move over.

When asked if he will keep on fighting past 50, he replied: "I'm happy enough to do that because I take care of myself."

Tyson fight

It had been rumoured earlier in the year that the two-weight world champion could be set to renew rivalries with Mike Tyson - the man who was disqualified in their last meeting for twice biting his rival's ear.

However, Holyfield insists a third meeting between the two ring legends was never likely because of Tyson's lack of desire to box again.

"I don't think that fight would actually happen. Mike doesn't really want to do it and I really don't want to fight a person who doesn't want to fight," he said.

"There wasn't any negotiating. It was a thought by someone. They thought 'if we get the weight off Mike this fight could be a great fight, because everyone would make money.

"It's one thing that the fighters make money but people realise that when you have two great fighters coming together, a lot of people make money."

Haye, however, could certainly be an option for the 47-year-old, meaning a meeting of two men who have successfully stepped up from cruiserweight.

Holyfield admits to being impressed by what he has seen of the Londoner, who achieved something he could not do by recording a victory over giant Russian Nikolay Valuev.

"Right now what he needs is experience," Holyfield said of Haye. "He can box and has a passion for it. He's the type of guy that trains and works hard, so there is no reason why he shouldn't be successful.

"If you look at David Haye then size doesn't make a difference - he's proven that by beating a guy at 7ft. He came up with a game plan to succeed (against Valuev).

"I fought big guys. Some I won, some I lost. The point is about making the adjustments, and David had everything to do that and win."
