Novak Djokovic has revealed that he is happy with his current form.

The world number one was speaking after he had extended his winning run at the China Open to 23-0 following his 6-3 6-4 victory over Andy Murray earlier today.

"I'm glad that I'm back in the form that I would like to be in, especially in these courts where I still haven't lost ever since I played this tournament. Hopefully I can finish the year in style, similar as I finished last year," the ATP's official website quotes the Serbian as saying.

Djokovic, 27, has now beaten Murray in six of their last seven meetings.
