I always ask myself why old heavyweights come back, but I plan to stay out of the ring.

I've worked hard and accomplished what I've accomplished in the heavyweight scene.

[Wladimir] Klitschko has got the experience, so if Tyson [Fury] waits on him, Klitschko will out-box him. But if he uses his speed and reach it will be a great chance for him to win.

You can just fight one man at a time.

The fight will last as long as I allow it to last.

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.
