Murray win never win against Murray again

Murray has become the new Nadal for Murray. He will lose to him every time from now on. He'll have his occasional triumphs, but more often that not, Murray will lose to himself and disappoint his fans on every occasion.

Yes, I know what you're thinking; I'm half joking/half-not. It's getting really bad, his attitude has somehow gotten even worse than when he was 20, and it's having a visible impact on his game.
