Khan: I want to be in big world title fights

This is my chance to prove once and for all that I'm the best in the division.

I can win the WBC title and will have held three of the four belts in the light-welterweight division, so it's time to move up to 147lbs.

I just think there are more challenges out there for me in that division.

I want to be in big world title fights and in big fights with the likes of Mayweather. To do that, I need to be up in that division.

Watching Mayweather's last fight (a points win against Miguel Cotto), coupled with the way I've been training, I think I'm ready.

One of the reasons I want to move up to 147lbs is to fight Mayweather and it's not about the money, it's about me knowing I can beat the guy and be the next guy at the top, the next pound for pound champion.
