I'm quite shocked by the recent British media stories about an alleged brawl between myself and Dereck Chisora. I am a professional prize fighter and let my fists do the talking only inside the ring. I don't want to comment on Chisora's psychological issues.

It was like a musician playing notes. Everything we trained worked.

These nuclear plants are more dangerous than people realize.

I will teach you how to behave yourself in the ring.

I'm boring but effective.

I train six days a week for four to five hours a day. I like to keep the same schedule when I'm in camp for every fight.

Politics is comparable to boxing. The only thing is that in politics there are basically no rules. In boxing, you can get a black eye, but in politics you can get poison in your food or a bullet in the head. It's definitely rougher and tougher than other sports.
