I think Murray has the best chance of his life today and I think he might do it, only bet ive had at Wimbledon was 9/4 Fed to beat Djokovic but Federer thought that was job done.
Murray has a chance, hes beat Federer before so you never know, Federer isnt the same Federer from a few years ago when he was unbeatable in a game like this.
Saying that, Federer is playin some quality stuff just now.
