Andy Murray: 'I'm not an angry person, I've never punched anyone'

British tennis number one Andy Murray has insisted that the public perception of him is far from what he is like in reality.

The Scotsman has often been referred to as moody and aggressive, but the US Open champion has claimed that he is a lot more mellow away from the court.

"As a person, I'd say I'm fairly relaxed," Murray told GQ magazine. "I am still extremely motivated and driven when it comes to my sport, but I wouldn't say I'm an angry person. People might think I am aggressive, but I have never punched anyone in my life.

"I would say that I am different from what a lot of people think I am like. What would bother me is if the people around me started telling me that I had begun changing, being an arse, or something."

Meanwhile, Murray is a doubt for this year's Wimbledon after he was forced to withdraw from the French Open with a back injury.
