Man up indeed. He behaves like a fucking child and I agree he seems to only want "yes" men around him, he dumps coaches with alarming regularity.
He could and should pump players like Wawrinka and as Hebrew says, you know right off the blocks what kind of match you're getting from Murray. He won't win a slam with that, he has all the talent in the world but a mentality that has the breaking strain of a fucking kitkat.
