Khan wants to 'clean up' division

British boxer Amir Khan says if he defeats Danny Garcia in this weekend's unification fight he will "clean up" the division.

Khan has had his WBA light-welterweight belt reinstated by the governing body and will put it on the line when he fights WBC champion Garcia in Las Vegas on Saturday.

If the Bolton-born boxer is victorious he will have won four out of the five belts in his division, with just the WBO title eluding him.
