You can train your mental strength just like you train your body. If your body looks fit or ripped, it looks strong, and you can flex your muscles. So, physically, you have a certain strength. Mentally, it's the same thing. You can train your psychological strength.

I never fought in my life outside of a ring.

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.

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

It is incredibly difficult to adjust to such a little fighter. Mormeck is similar to Mike Tyson, he is just a little still faster.

I think a fight with David Haye, even if he is not American, is going to give positive vibes about the heavyweight division for the American fans and fans worldwide.

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.
