I'm playing right now a role, and the role is called the 'Heavyweight Champion of the World.' And it takes all of the time. And I love this role, and it takes a lot of attention for me for the sport, and I just don't want to lose the title, so that's why I have to stay focused and not become an actor.

Aggression means emotions. Emotions means you’re gonna get off your plan and that means you’ll lose the fight.

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 have decided to make a personal message to David Haye. I want him to fight me, to be a man. I wish there will be enough excitement, pressure and courage for David Haye to fight me.

Criticism is a great motivation. Failure is not an option to me.
