Amir Khan has Floyd Mayweather in sights

Amir Khan has targeted a bout with the undefeated Floyd Mayweather.

The 24-year-old defeated Zab Judah in Las Vegas on Saturday to take the IBF crown to go alongside his WBA title.

Khan will chose from a shortlist that includes Mexican Erik Morales and WBC and WBO title-holder Tim Bradley before moving up to the 147lbs division and opting for a Mayweather bout.

"My aim is to move up the pound-for-pound rankings and to one day be pound-for-pound champion,” Khan said.

"The Mayweather fight is something I'm looking at for the future and it would be huge for me. It would drive me on."
