Amir Khan learnt first hand that there's always someone out there harder than him.
He may be a skilfull boxer but that counts for nothing when his opponent puts him on his ar$e before he has the chance to use those skills.

A very steep learning curve.

Frank Warren, looks like he gambled and lost, big time! Who's gonna pay to see Khan contest his next fight against his more usual opponent (probably a no hoper)
Couldn't have happenend to a nicer guy. Warren is a parasitic snake who feeds off boxers. He's made vast amounts from staging events, makes sure he gets his face on the telly at every given opportunity. Personally I can't stand the smug faced crook!
