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.

When you're successful for so many years, the scariest part is that you're getting too comfortable because you've had so much success.

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.

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.

The challenge for me is his size because, for the first time in my career, I'll be meeting an opponent who is taller than me and has a longer reach.

I train six days a week for four to five hours a day. I like to keep the same schedule when I'm in camp for every fight.

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