Adversity is something that makes reaching your goals so much more rewarding than if it didn't exist.

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

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.

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 fact is that Mike Tyson bit through my trousers and took a significant piece of flesh out of my thigh.
