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

My goal is not getting hit and to knock the other guy out. Some people might complain because they want to see boxers beat up on each other, but you cannot last long in professional boxing if you take a lot of punches.

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

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

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'm trying to keep the face of my opponent more or less not damaged but eventually to execute the plan and knock him out.

[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.
