Gotta love having microphones and extra cameras on court at the US Open. All the clips of Andy Murray moaning in his Nadal semifinal match I put together in one clip. So hilarious, watch it to the end - it gets funnier. http://www.youtube.com/watch?v=k8koEx2OUa0 But on a serious note, is this why Murray can't win a slam - Mental concentration and behaviour? So much energy wasted shouting at his box that the opponent feeds off it (Nadal) and makes them play better?
