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

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.

Radiation doesn't recognize borders. A meltdown in Japan or India, say, is a danger to the whole world. Wind circulates the radiation everywhere. Water quality is affected. We all eat the same fish. We use products from all over the world - if something is contaminated, it will cause harm.

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 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.

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

There's certain things that you cannot cross, no matter who you are, what you're doing or where you're coming from.
