Amir Khan has improved leaps and bounds since he went to the US to train under Roach . This now, and always has been, an essential move for UK boxers. They learn rhythm and timing and defence,which our coaches don`t seem to be able to repeat. The exception being Enzo and Joe Calzhage.
Over the years our really stylish World champions like Terry Downes and Ken Buchanan all had this benefit.
A lot more to come from Amir in my view, as he has incredible natural speed.
