Andy Murray's coach and former world number four, Brad Gilbert, believes the young Scot has the ability to become a top quality grass court player.
Murray's play on American hard courts this year has seen him tipped to be a future US Open winner, but Gilbert thinks Wimbledon is as likely a venue for a Murray Grand Slam.
"He (Murray) has the ability to return serve and move well." Gilbert told the Independent.

"It's sometimes a question of your mindset. At the moment he thinks grass is not his favourite surface, but as he gets older and more experienced I think he'll show how well he can play on grass"
"The thing that's surprised me more than anything is that I didn't realise his hands were as good as they are. He looks like he has the ability to become a great net player."
Gilbert also talked about Murray's now infamous temper, but the American has not pin pointed it as a big concern
"He is what he is," said Gilbert, "he's never going to be a choirboy. That's not his personality. Sometimes when he's flat it does help him to get fired up. Sometimes it doesn't.
"Everything is about balance. I think it's a lot better to express your anger than to sit there holding it in."
"For a kid who's 19 Andy has a pretty solid head on his shoulders. He's not a wild and crazy guy."
