Maybe Murray has something new up his sleeves. A new game plan to take down the top 3.
Would be cool if he was to adopt the Nalbandian game. You know, a fitter, faster and taller version of Nalbandian would be quite a handful, even for the top 3.
At his best, like in Tokyo, he can and he'd have to play that Nalbandian/Davydenko style against Nadal, and then he can really cream the guy, but he's not in that form really often. Usually he starts spraying and gets frustrated.
Against Nole and to a lesser extent Fed, it's a different story- his normal, patient, variety and defensive skill actually trouble them without much tweaking. He has to believe in himself in the big matches- that's the most important thing.
