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.

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.

The whole key is to be honest with yourself, find the weak spots, work on it, get it done.

I'm boring but effective.

In the old days, when Muhammad Ali was fighting Ken Norton, Joe Frazier and George Foreman, there was a lot of excitement in the heavyweight division, I have to admit it.

Sometimes it's boring because it takes time, but it's enjoyable. So beating up people for a living is really fun.

You have to learn the opponent psychologically inside out and mental strength is one of the important makers. You're either gonna break it or make it.
