Novak Djokovic: 'Winning first set was key'

Novak Djokovic has said that winning the first set in his Paris Masters quarter-final against Andy Murray gave him "an edge" over the British number one this evening.

The two players could not be separated for much of the opening set, but a double fault by Murray while serving at 6-5 down helped the world number one clinch the set, before going on to win the match 7-5 6-2.

The Serb told Sky Sports News: "We have played so many times. We know what to expect. It will be physical with long exchanges and whoever is calmer in the important moments and comes up with the big shots can prevail.

"He was a break up in the second, but he made some mistakes, made some double faults and allowed me back in. Then I was swinging through and I felt better.

"I don't think the physical factor played an advantage for me too much, but I think maybe winning the first set gave me an edge."

Djokovic, who is the defending champion at this event, will face the winner of the match between David Ferrer and Kei Nishikori tomorrow for a place in the final.
