I'm going to give him a pizza face.

Criticism is a great motivation. Failure is not an option to me.

I've fought everybody without ducking anyone. I have beaten 10 undefeated guys, and I never was comparing myself to the greatest in the sport. I was not thinking of breaking any records. I'm just enjoying my time in boxing.

I heard that I am crazy for taking this fight but I'm very excited about this chance. His manager is saying that I'm a 'dead man walking' but 'dead men' cannot have 'nightmares'.

Mental strength is really important because you either win or lose in your mind. And I'm not solely talking about sporting matches, boxing events - anything you do, you do it first with your mental strength. And you can actually train and develop it, and I am responsible for what I'm saying because I have experience with that.

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.

I'm quite shocked by the recent British media stories about an alleged brawl between myself and Dereck Chisora. I am a professional prize fighter and let my fists do the talking only inside the ring. I don't want to comment on Chisora's psychological issues.
