My brother is a doctor and he will take care of post-traumatic stress. I think he'll do it for free.

I don't care where people come from. It is not important to me. If you are good people will like you, if you're not, they won't. It is simple.

I've been many times to Dubai and the U.A.E., and I have friends that live there. It would be exciting to stage world heavyweight championship fights in the Arab world. It's something Muhammad Ali achieved when he fought in Zaire or the Philippines. It's absolutely exciting to fight in countries where you have never fought.

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'm boring but effective.

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

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.
