Novak Djokovic has been ‘unbelievable’ in 2015, says Thomas Enqvist

Novak Djokovic has been proving himself as an “unbelievable” talent with his sublime form in 2015, according to former world No4 Thomas Enqvist.

The Serb’s stunning year continued when he triumphed at the Shanghai Masters and is the heavy favourite to retain his title when he competes at the ATP World Tour Finals in London next month.

“It’s difficult to not say Djokovic after he has dominated this year,” said Enqvist.

“In the last two tournaments in Asia, he won Beijing without losing more than three games in one set and it went the same way in Shanghai as well. He’s obviously unbelievably confident and playing the best tennis of his life.

“When he gets on those rolls it’s very difficult to stop. This is his best season ever. He’s even more complete than he was in 2011. He’s developed his game even more I would say.

“It’s also interesting to see if Federer can keep up the level of tennis he played this summer. Indoors he also plays very well, so if he can play close to how he did in the United States, he can win (at the O2).

“He’s unbelievable. It’s just amazing to see what he’s doing.”
