Evander Holyfield has reiterated his desire to step into the ring with either of the Klitschko brothers.
The four-time world heavyweight champion has dismissed talk that, at 49 years of age, he is too old to challenge the dominant Ukrainians.
Holyfield, who is currently struggling with financial issues, has claimed that a bout will be the biggest payday of their lives.
"Age ain't nothing but a number," Holyfield told Sky Sports News. [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.
"I said make sure that guy wants to fight me, because I don't want it to look like I fought that older guy, but that he fought me. With the Klitschkos, they aren't choosing to fight me, I've said I'll fight them. All they got to do is realise that both of us will make money, then we'll see who the winner is."
Holyfield won WBA, WBC and IBF titles in the cruiserweight and heavyweight divisions.
