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.

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.

He [Tyson Fury] will be difficult opponent to adjust to, because of his style of fighting and physical conditions. Fans will certainly not be bored.

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

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.

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.

In Soviet times the border was closed so we couldn't get out of the country, and I had been reading Robinson Crusoe. I wanted to see the ocean, I wanted to see boats, I wanted to see black people, because we didn't have that in the Soviet Union. I was all excited by that stuff.
