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

It is up to the people and boxing fans to give me the respect I deserve once I have finished my career. I personally do not think about my legacy.

All the champions - you go and ask Mike Tyson or Joe Louis, Rocky Marciano, Lennox Lewis and myself included, and I'm sorry for putting myself in line with all the other great names - but the champion's attitude is it doesn't matter who is in front of me, I am going to conquer this person and win the fight and knock the person out.

The man wannabe actually...a wannabe. David Haye's a wannabe.

From nothing to everything is a long way, from everything to nothing is one stop.

I always train and prepare with highest concentration and focus on my next opponent. To me, it does not matter what his name is.

I should say that mental strength is No. 1, experience [is] No. 2, physical strength is No. 3, and genetic ability that you're getting from Mother Nature probably comes after.
