Nadal 11-5 Del Potro

Playing styles
Del Potro: A brutally physical style of play almost cost the Argentinian his career, but he returned from four wrist operations with a new backhand and a more rounded game.
Nishikori: The Japanese player is famous for his mental strength and hits compact and powerful strokes on both forehand and backhand, which allow him to play closer to the baseline.
Djokovic: A big serve, incredible movement and a phenomenal backhand have brought the Serbian former world number one 13 career grand slams so far.
