Andy Murray has said that previous triumphs over Novak Djokovic will help to spur him on against the Serbian when they meet in the US Open quarter-finals.

The British number one defeated Jo-Wilfried Tsonga 7-5 7-5 6-4 yesterday to set up a meeting with Djokovic at Flushing Meadows.

Asked if edging out his opponent in two of their last three Grand Slam meetings will play a part in the latest clash, Murray told Sky Sports News: "They obviously will help. I wouldn't say in terms of getting confidence, it's just having that experience of playing those matches.

"They were both very long, tough matches, as well so I know that I can last those matches against him. But anything can happen in a couple of days. I'll just do everything properly and hope on Wednesday I play a good match."

Djokovic reached the last eight in New York by easing past Philipp Kohlschreiber.
