Mental strength is really important because you either win or lose in your mind.

[Anthony Joshua] is the best man in the division and I believe this excitement speaks for itself. This is what the fans want and this fight must happen.

I've been doing this 26 years and have a lot of knowledge which will help me in the ring.

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

There is no money in this world that will make us fight.

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.

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.
