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

[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 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.

When you're successful for so many years, the scariest part is that you're getting too comfortable because you've had so much success.

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.

I would say that Roger Federer is pretty amazing. And Manny Pacquiao - he's such a tiny, little lightweight guy, but the way he fights makes people so excited.
