I would say that Roger Federer is pretty amazing. And Manny Pacquiao - he's such a tiny, little lightweight guy, but the way he fights makes people so excited.

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

I never fought in my life outside of a ring.

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

He [Tyson Fury] will be difficult opponent to adjust to, because of his style of fighting and physical conditions. Fans will certainly not be bored.

The first thing I learned in boxing is to not get hit. That's the art of boxing. Execute your opponent without getting hit. In sports school we were putting our hands behind our backs and having to defend ourselves with our shoulders, by rolling, by moving round the ring, moving out feet.

I'm boring but effective.
