I'm going to give him a pizza face.

You have to learn the opponent psychologically inside out and mental strength is one of the important makers. You're either gonna break it or make it.

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

All of my fights are planned. I study my opponents from A to Z. How he walks, how he looks, how he speaks, gestures of the human body, which is a certain language that provides you lots of information if you have the ability to read it.

I should say that mental strength is No. 1, experience [is] No. 2, physical strength is No. 3, and genetic ability that you're getting from Mother Nature probably comes after.

On your way to the top, you always get some chriticism. Criticism is a great motivation.

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.
