I learned in my Ph.D. the discipline I needed to be successful. Most boxers are not that disciplined.

My studies were about the control of training on both the psychological and the physical side.

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

This guy [Tyson Fury] really wants to prove himself in the ring and confirm what he keeps telling everyone, that he's the best in the world.

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.

From nothing to everything is a long way, from everything to nothing is one stop.
