A relatively decent performance, but he is going to be peeved that he wasn't able to push Nadal harder. Nadal is an exceptional player and he owed Murray a defeat.
Nadal is too good, not just for Murray but for everyone that currently plays the game and has ever played the game. He was the better player and it shall always remain that way.
Ask for Murray he could do know more. He actually won more points than Nadal and still lost! The main reason he lost out was his forehand, which can't cope with the Nadal spin. Murray has to either hit it a fraction over the net or a fraction on the Baseline and to do that every point is simply unrealistic. Well done Rafa.
