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

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.

Defeat will help you. I've been there and done that. I shook it off and came back stronger. It's nothing to be scared about.

It's not my place to compare myself to greats like Tyson, Frazier or men like that. But I would look at a fighter like Evander Holyfield. He's a great heavyweight who worked his way up through the weight classes to become champion and had to beat bigger men along the way.

If I am 100% prepared for the fight, my opponent has no chance to win the fight. I am saying what I mean: He has a 0% chance to win the fight. There is going to be no luck involved; there is going to be nothing else to stop me from winning the fight.

I've fought everybody without ducking anyone. I have beaten 10 undefeated guys, and I never was comparing myself to the greatest in the sport. I was not thinking of breaking any records. I'm just enjoying my time in boxing.

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.
