Vitali [Klitschko] does want to fight me, but his promoter wants to be bigger than him. This is another situation of politics in the sport.

Boxing involves the possibility of defeat, I accepted that very early on. After all, there are only two men and one of them wins.

I wanted to prove I was the best fighter in the world.

For me, there's never any bad blood - unless you do something to me.

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.

Mike Tyson fit the American ideal of a boxer. A fighter who jumps out of his corner and hits out fiercely. That’s what he’'ll be remembered for. But good boxing doesn’t work like that. Tyson never won on points. It was clear that he’'d come a cropper some day.

I am definitely not scared of Mike Tyson. I am at the top of the food chain and he is looking to knock me off. Mike's an arrogant imbecile. He sounds like a cartoon character.
