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.

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.

That's the most terrible mistake you can make: to relax. It's difficult to become a champion, but it's more difficult to maintain it for many years because you're getting too comfortable.

You lose or you win the fight - and anything in life - in your mind. I can look at how the person walks, how he speaks, his expressions. It's a wisdom. Eyes are the mirror of the soul. So you can read a lot.

There's certain things that you cannot cross, no matter who you are, what you're doing or where you're coming from.

Aggression means emotions. Emotions means you’re gonna get off your plan and that means you’ll lose the fight.

I would compare it to an actor. I drive myself into the character that later on is in the ring.
