Fighters used to be afraid of the Russians, Cubans but then I'd figure them out and figure out how to beat them.

When I was fighting Tyrell Biggs, Tyson was telling me at ringside to hit him to the ribs. We always had a mutual respect for each other since we sparred those early times. We got that over with.

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.

There is just one rule about boxing: never bet on the white guy.

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

I am definitely not scared of Mike Tyson. I am at the top of the food chain and he is looking to knock me off. Mike's an arrogant imbecile. He sounds like a cartoon character.

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.
