In preparation for his upcoming UFC title defense against former Strikeforce welterweight champ Nick Diaz at UFC 137, Georges St-Pierre has once again turned to boxing’s best trainer Freddie Roach.

Roach, known as the head boxing coach to champion Manny Pacquiao among his many other accolades in the sport. St-Pierre has credited Roach in the past for his improved stand-up following the decimation of Josh Koscheck with a much evolved striking game.

Can Freddie Roach help St-Pierre find that knockout power well cracking the counters to Diaz’ unorthodox striking?
