You silly, silly, ??? Khan is nothing. All that Britain has is Tyson Fury to a degree and Prince Patel.
Mayweather. Even an old Mayweather is far more skilled, takes a better shot, and perhaps most importantly, is light years ahead of Khan in boxing IQ.
Please. If Mayweather come to England, he would be severly weakened by the proper PED testing and Ian John Lewis would have seen enough in round 6 when Mayweather is taking 6 unanswered pitty-patter punches against the ropes. :deal Mayweather barely got by Khan's son Maidana for christ sake.
Mayweather beats Khan regardless of what Khan turns up. Khan can't cope with timing, Khan gets tagged because he can't time coming in, Mayweather has the lot, great footwork and great timing so it only ends one way. Shall we go through the list of fighters to either drop Khan or seriously hurt him? Khan's handspeed wasn't much use then so stop with all this "Khan's speed" cobblers.
A guy who was dropped by Willie Limond beats Mayweather ROFL Khan would get smashed and knocked out fast. Very fast.
