Novak Djokovic says there is still room for improvement

The 29-year had joined Don Budge and Rod Laver as the only players to possess the Australian Open, the French Open, the Wimbledon, and the US open simultaneously after he beat Andy Murray in the French Open final. The Serbian is well on his way to achieve a ‘calendar slam’ with the World No.1 the favourite to lift the Wimbledon and US Open.

"Obviously, I'm at the peak of my career at the moment. I see still lots of room for improvement, things that I can work on," Djokovic said, reported AFP.

"I can certainly say I've been working hard to get consistency on all kinds of surfaces," he added.

"Pressure is part of what we do. It's inevitable to face this kind of sensation as a top player," said the 29-year-old.

"But the more you get to face this kind of pressure and emotions, the better you are in coping with it and handling it.'

"Of course, the situation this year is quite different from previous years because I'm coming in with a Roland Garros title for the first time.

"That gives me a lot of confidence prior to this event," he said, reported AFP.

"I would say Andy Murray and Roger because of their rankings, their history of playing well, and winning this tournament, especially Roger for so many times," Djokovic said, reported AFP.

Djokovic is likely to face Roger Federer in the semi—final of the Wimbledon with both players in the same half of the draw, while Andy Murray, who is on the other half, is likely to face Stanislas Wawrinka in the last four.
