There's certain things that you cannot cross, no matter who you are, what you're doing or where you're coming from.

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.

Nobody is born as a champion. You have to earn it through hard work. Get started!

I know he's retired, but I'm a big fan of Shaquille O'Neal, his game and his personality. I have a pair of his shoes in my office. You see the size of his shoe and think, 'This is not real, this couldn't belong to a human being.' But he is human!

All the champions - you go and ask Mike Tyson or Joe Louis, Rocky Marciano, Lennox Lewis and myself included, and I'm sorry for putting myself in line with all the other great names - but the champion's attitude is it doesn't matter who is in front of me, I am going to conquer this person and win the fight and knock the person out.

I would compare it to an actor. I drive myself into the character that later on is in the ring.

I think that boxing is actually not as dangerous as the politics. In boxing, you're gonna get a bloody nose or a black eye. In politics you can obviously get either dioxin in the food or bullet in the head.
