Nadal looking ahead to 2017 after shock defeat

Rafael Nadal says he is now focused on 2017 after being beaten by Viktor Troicki at the Shanghai Masters on Wednesday.

The Spaniard went down 6-3, 7-6 (7-3) to World No 31 Troicki in the second-round clash, and is now in danger of missing out on qualification for the season-ending ATP World Tour Finals for the first time in 11 years.

Nadal admitted he is not playing his best tennis at the moment, and must start looking ahead to next season.

"I need to create pain for my opponent. It is something that is not happening very often now," he said.

"I've two and a half months to put myself at the level I need."

Nadal has identified a newfound weakness in his forehand, and is confident that he will return to winning ways if he can rediscover his power on that shot.

"I need to recover the forehand. I know I need to hit forehands," he said.

"I need to move faster to hit more forehands. But I need to be more confident with the forehand to make that happen. Everything is a cycle."

Nadal has now failed to make the semi-finals in the last four tournaments he's played in, a rare occurence for the 14-time Grand Slam champion.

Meanwhile, Andy Murray had no such problems in Shanghai on Wednesday, easing into the third round with a 6-3, 6-2 victory over American Steve Johnson.
