The first thing I learned in boxing is to not get hit. That's the art of boxing. Execute your opponent without getting hit. In sports school we were putting our hands behind our backs and having to defend ourselves with our shoulders, by rolling, by moving round the ring, moving out feet.

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.

I think a fight with David Haye, even if he is not American, is going to give positive vibes about the heavyweight division for the American fans and fans worldwide.

Only younger brothers will understand me. We're following in the footsteps of older brothers. You are looking up to your brother. You want to do the same things. You want to do as good as he and do it even better.

My father told and taught me that the word, can hit harder than the fist.

The whole key is to be honest with yourself, find the weak spots, work on it, get it done.

From nothing to everything is a long way, from everything to nothing is one stop.
