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.

Who's gonna win between two brothers? The Klitschko mother's gonna win because she said it won't happen.

It's such a gift in my life to be able to compete - to have the health.

Mental strength is really important because you either win or lose in your mind. And I'm not solely talking about sporting matches, boxing events - anything you do, you do it first with your mental strength. And you can actually train and develop it, and I am responsible for what I'm saying because I have experience with that.

It is up to the people and boxing fans to give me the respect I deserve once I have finished my career. I personally do not think about my legacy.

When people are tipsy, they're really encouraged and they wanna prove they can do something to the Heavyweight champion.

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.
