ANDY Murray has been offered some advice from tennis legend and 17-time Grand Slam winner John McEnroe – get angry.

McEnroe, whose violent temper during his playing career earned him the nickname Superbrat, claims the Scots ace – who often seems to let his feelings get the better of him on court – could turn his emotions to his advantage.

The sporting veteran, who caused a storm during his first Wimbledon victory in 1981 when he kicked his own racket, told Radio Times magazine: "Anger should be fairly straight- forward.

"If you use anger in a positive way, where you get yourself to try harder and dig deeper, it can be a good thing. I would often get mad at myself to try to increase my intensity level, so if Murray could use that in a way where it wouldn't hurt his game, I think it'd be a good thing."

McEnroe said that despite not always handling his out-bursts as well as he could have, his emotions helped him to succeed.
