It's such a gift in my life to be able to compete - to have the health.

I learned in my Ph.D. the discipline I needed to be successful. Most boxers are not that disciplined. They have talent, but the self-organization - the ability to schedule yourself and your priorities - is lacking. My studies were about the control of training on both the psychological and the physical side.

When people are tipsy, they're really encouraged and they wanna prove they can do something to the Heavyweight champion.

There are 49 guys that got bored to sleep on my record, so they got knocked out by it.

[Anthony Joshua] is the best man in the division and I believe this excitement speaks for itself. This is what the fans want and this fight must happen.

It was like a musician playing notes. Everything we trained worked.

He's been an inspiration for me since the Olympics 1996.
