Former Heavyweight champion Evander Holyfield wants to prove he is one of the best boxers there has ever been and fight one of the Klitschko brothers.
The 49-year old is ready to challenge either of the Klitchso brothers and says it could be the biggest payday of their lives.
He dismissed the idea that he is too old to challenge the dominant Ukrainians.
"Age ain't nothing but a number," Holyfield told Sky News correspondent Tom Parmenter.
"The Klitschkos have got an opportunity to probably make the biggest payday of their lives fighting Evander Holyfield.
"They are telling everyone that they respect me, and that they don't want to beat me up - but I fought George Foreman, I fought Larry Holmes, and I said the same thing. I said that I wouldn't get any credibility from beating someone older."
