Andy Murray is wary of the threat that Fernando Verdasco will pose in their quarter-final clash at Wimbledon tomorrow.

Despite leading in a head-to-head record 8-1, the Scot believes that the Spaniard is a potent opponent.

Murray told reporters: "Verdasco is a very, very good tennis player. He's playing very well this week. He's extremely dangerous when he's on his game."

The 29-year-old defeated the British number one in the fourth round of the Australian Open in 2009.
