I'm undisputed and there's no disputing that.

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.

After about 25 fights you don't always have to keep going to the bathroom before the fight.

If the media didn't know I played chess, there'd be no angle on me at all.

[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.

The fact is that Mike Tyson bit through my trousers and took a significant piece of flesh out of my thigh.

The mission I set out on in the beginning - to become heavyweight champion of the world, undisputed, lineal champion - you could say that mission is complete.
