It's a very interesting fight [Klitchko vs Tyson Fury] because this is the first time [Wladimir] Klitschko is fighting someone as big as him and with longer arms. He will have to be a little bit more aggressive, otherwise the younger guy will have more speed and more energy and I think that may be the difference.

I think Kirk Johnson is a more exciting fighter than Chris Byrd. A lot of people agree with me when it comes to that.

After about 25 fights you don't always have to keep going to the bathroom before the fight.

I am proud to be in Los Angeles. I have a lot of fans that love me here. When you talk about the Meccas of boxing - Las Vegas, New York - now you have to talk about Los Angeles.

At first I didn’t give a damn to go down in history. I wanted to win. But the more I won, the more I thought about leaving something behind. Yes, it's as important as hell to me. I want to leave something that people will remember me by. Of course, a lot of boxers want to do that. But it's not easy. Take Larry Holmes, he was the big man after Muhammad Ali, he wanted to emulate him, but for some reason the public didn’t take him like they did to Ali. I think people won’t fully understand what I contributed to the sport for years.

If you’ve got physical weaknesses, you’ll lose. Nobody who gets cut easily can be a champion, however strong and talented he is. Boxers are trained to see and exploit their opponents’ weaknesses, they hit you on your wounds. Only the strongest survive in this sport.

In boxing you create a strategy to beat each new opponent, it's just like chess.
