Andy Murray, who lost to Novak Djokovic in the final of the Paris Masters in straight sets, is now 1-6 against the Serb this year. This season Djokovic has won six ATP Masters 1000 titles and three Grand Slam titles; Murray's lone victory over the world No. 1 came in the Montreal Masters final. Over his entire career, Murray is 9-21 against Djokovic.

"Obviously this year [Djokovic's] level has been incredible," said Murray, who is also 0-2 against Roger Federer in 2015. "Since the beginning of last year, my results against him and Roger, from my perspective, haven't been good enough. I need to do better in those match ups. It's harder playing against the best players. Those two are two of the greatest players of all time, so there is no disgrace in losing to them. But I do feel like I need to start doing better in those match ups, because the scoreline in the last couple of matches there hasn't been good."

The No. 2-ranked Murray has won two ATP Masters titles in 2015, at Madrid and Montreal. The 28-year-old reached the final of the Australian Open, losing to Djokovic. He also lost to Djokovic in Indian Wells, Miami, Roland Garros, Shanghai, and Paris.

Murray will play the ATP World Tour Finals in London next week, and could finish as the year-end No. 2 for the first time in his career. He will also lead Great Britain in the Davis Cup final, in Belgium, the following week.
