Nole wasn't acting like he was on the brink of death at the start of the 2nd set?
Thats because he had problems, just like in his match against Ferrer in 2nd set. He was running slower for a set and a half, couldn't hit a single first serve, Murray had a lot more winners in that period. Why didn't he acted like that in last 2 sets? ? don't want to argue after a great match, think what you want but that is not acting.
