I am the heavyweight champion of the world, and the greatest heavyweight you have seen for a long while. With Tyson on the card, it is definitely an added bonus because Lewis-Tyson on the same card would be a great doubleheader. This is what the fans want to see.

If I don't feel the same hunger as I once did then I definitely shouldn't box any more.

I play chess about four hours a day in training camp. You have to decide what move to use, or what combination of moves. I think less when I box because the reaction time is a lot quicker, but some people call me the chess boxer because they say I think too much in the ring. I take my time and they don't see the action they want. Some boxers just go in there and just throw punches and hope to win.

[Wladimir] Klitschko has got the experience, so if Tyson [Fury] waits on him, Klitschko will out-box him. But if he uses his speed and reach it will be a great chance for him to win.

Recently I donated money to the establishment of the Muhammad Ali Foundation in Louisville. I regard that as a kind of payback. He smoothed the way for us. He wasn’t just a great person who had conviction, but made the sport of boxing great. He was the first superstar, he made our stock rise. Without him we wouldn’t have earned so much. Americans from every walk of life have contributed to the foundation: Bill Clinton, Angelina Jolie, Brad Pitt. Unfortunately I was the only American athlete to make a donation. There’s not enough respect in our business.
