I always train and prepare with highest concentration and focus on my next opponent. To me, it does not matter what his name is.

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.

I prepare for my fights to well that I don't wanna give a chance to my opponent to crash my 'glass chin' as they say, so I'm knocking them in the way that I like.

I respect the IBF obligation to fight Povetkin, but I would like the exception to fight David Haye. That is the only title the Klitschkos don't have. We have them all except the WBA, which is why Haye is such an interesting cookie for me to eat.

That's the most terrible mistake you can make: to relax. It's difficult to become a champion, but it's more difficult to maintain it for many years because you're getting too comfortable.

My father told and taught me that the word, can hit harder than the fist.

You lose or you win the fight - and anything in life - in your mind. I can look at how the person walks, how he speaks, his expressions. It's a wisdom. Eyes are the mirror of the soul. So you can read a lot.
