The first thing I learned in boxing is to not get hit. That's the art of boxing. Execute your opponent without getting hit. In sports school we were putting our hands behind our backs and having to defend ourselves with our shoulders, by rolling, by moving round the ring, moving out feet.

Obsession is love in an extreme shape.

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.

Mental strength is really important because you either win or lose in your mind.

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.

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.

Mental strength is really important because you either win or lose in your mind. And I'm not solely talking about sporting matches, boxing events - anything you do, you do it first with your mental strength. And you can actually train and develop it, and I am responsible for what I'm saying because I have experience with that.
