That is one of the most annoying things about Andy Murray, he swears and gets frustrated when an opponent hits an ace or a winner that no man on earth can return/get to. Sometimes, champions have to nod their head and just say "too good."
This is why Murray will have a hard time getting to no.1 and winning multiple slams. He spends way too much emotional/mental energy on court over things he has no control over (like opponent hitting an ace or a great winner).
Federer usually just remains silent. Rafa will sometimes nod in approval. Nole applauds great shots. Murray has a lot to learn from those 3 players if he ever wants to be like them.
The mark of a true pusher/defensive player: "I SHOULD have returned that unreturnable shot. Whether it be an ace at 413 MPH or a winner that was hit while I was still in the locker room. I SHOULD have got to it."
Can't stand him
