Nadal wary of dangerous Muller

Rafael Nadal has claimed Luxembourg's Gilles Muller will be a "dangerous" opponent when they meet on Court One at Wimbledon.

Nadal knows only too well of the threat posed, having lost to Muller six years ago at the All England Club.
In fact, Muller remains the only person other than Roger Federer to have beaten the defending champion since 2005.
And although Nadal has subsequently toppled Muller in their only other meeting since then, the Spaniard is refusing to underestimate his rival.
"I played six years ago, it was a long time, but he beat me," said Nadal. "That's what happened. He's a very dangerous player.
"He has a good serve and a good volley. He's especially dangerous on this kind of surface so it will be a tough match for me.
"I have to be very focused with my serve and try to convert the small chances I will have on the return."
