Murray reached the SF of RG with no coach, I was dissapointed with the score but he was extremely tired.
Murray has shown he can easily beat Roger and Noel on grass (Olympics and Wimbledon).
So if someone takes out Nadal for him I think he can easily win it again, Nadal did go out in the 1R last time and it is his weakest surface where as RG was his strongest so who knows.
Murrays biggest threat is Novak but hopefully he won't have to meet him until the final, I want Murray to win at least one slam this year!
