Well Murray has got a woeful record against Cilic, and IIRC grass suits Cilic so theres easier folk he could have played. Roddick loves Wimbledon and Gasquet is a bit of an unknown, ie which Gasquet will turn up, It's a lot more difficult than his draw at the French, but if he's got his head screwed on, he should manage it. I've seen no evidence to suggest that the top 3 will have to play their best against Murray to beat him. Has Murray beaten any of them in a grand slam? I'm almost certain he hasn't. It's all in his head, get that sorted and he could be going on a 46 match unbeaten run (or whatever it was) like Djokovic.
