Golovkin: Canelo is one of the dirtiest opponents I've ever faced

By Sean Jones: Gennady 'GGG' Golovkin ripped into Saul Canelo Alvarez this week in calling him the dirtiest fighter he's ever fought. Golovkin (38-0-1, 34 KOs) didn't go into details of what he meant by saying that Canelo is the dirtiest fighter he's ever fought, but it's possible that he's eluding to his two positive tests for the performance enhancing substance clenbuterol last February.
