Mike Tyson fit the American ideal of a boxer. A fighter who jumps out of his corner and hits out fiercely. That’s what he’'ll be remembered for. But good boxing doesn’t work like that. Tyson never won on points. It was clear that he’'d come a cropper some day.

When I saw Tyson knocking everybody out on TV, I thought, He's goooood. But when I saw him in person, he didn't look as awesome.

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.

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

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

Sometimes success needs interruption to regain focus and shake off complacency.

If I don't feel the same hunger as I once did then I definitely shouldn't box any more.
