I don't know how satisfied Murray should be. Lets face it, hes been pretty stuck at this stage for the better part of 3-4 years now.. He hasn't really progressed as a player. Hes been stagnant. Unable to break the shackles of the other 3 guys. One of those guys always get the better of him damn near every time.
I see no difference into where Murray is now compared to where he was in 2009 or 2010 or even last year.
Murray is obviously better than last year, nothing revolutionary like Djokovic last year but he has shown progress. Wait and see, he will cause trouble to Djokovic/Nadal this year.
