I think murray has had a problem with minor injuries for a while, back at the french last year he had similar issues with his back, spasms and stuff and they seem to creep up every once in a while. nadal has issues with his knees and he has made the most of it, it is really just bad luck that stopped murray from making the final closer (maybe even won it as he was so close to being 2 sets to love against Djokovic on his best surface). murray has improved since his slam win. he took it to Djokovic for 2 sets on his best surface, a surface that doesn't favor murray as much. he had a chance to win, as i have said already and i feel that with age he will mature even more. Murray is, i feel, a future number one. he just matures slower than Djokovic, Federer and Nadal. he will peak eventually and i feel that it is coming, if not already started.
If I could, maybe I'd give you my world.. How can I, when you won't take it from me?
