Djokovic revelling in 2015 form

Novak Djokovic believes 2015 has been the best year of his career and feels he is a more complete player as he goes in search of a sixth China Open title this week.

The Serb has been in remarkable form this year, having won three of the four major titles on offer, narrowly missing out on a calendar Grand Slam after losing to Stanislas Wawrinka in the French Open final.

With a few months remaining in 2015, the 28-year-old has set his sights on bettering his haul of 10 singles titles back in 2011, but already feels this has been the best year of his life.

"Somehow I feel like this one is even better," he said. "I just feel like a more complete person and a player.

"I’m a father and a husband, just different circumstances that happen in my life in the last couple of years that have helped me to enjoy all the success that I have on the tennis court even more. So 2011 was absolutely an incredible year.

"But I feel this year I’m enjoying it even more because I’m more, I would say, fulfilled, more complete, more mature as a person and a player."

Djokovic returns to the ATP Tour this week for the first time since winning the US Open as he turns out at the China Open before heading to the Shanghai Masters next week.
