Rory McIlroy says he is concentrating on a return to his best form, having regained full fitness as he chases a third Race to Dubai title.
The former world number one ruptured a ligament in his left ankle during a game of football with friends in July, ruling him out of several tournaments.
"I guess I'm more concerned about form than fitness at this point. My fitness is totally fine," said McIlroy.

"I'm pretty much back to where I need to be and I'm happy about that."
He added: "I've started to train the way I was before the injury. Now I'm trying to get my game back into the shape that I know that I can. I feel like I've made a few steps in the right direction."
This season's European Tour has four events remaining and McIlroy, who enjoys a 271,214-point lead over Danny Willett in the Race to Dubai, will play in this week's Turkish Airlines Open, the WGC-HSBC Champions in Shanghai and the DP World Tour Championship in Dubai.

'An opportunity to see where my game is'

McIlroy's injury ruled him out of the Scottish Open and the defence of his Open and WGC-Bridgestone Invitational titles.
The 26-year-old returned to action in time to defend his US PGA title at Whistling Straits and played in three of the FedEx Cup play-off events before starting the new PGA Tour season with a tie for 26th in the Frys.com Open in California.
"It would mean an awful lot to win the Race to Dubai," he added. "I had a great chance back in 2009 to win and didn't quite; Lee (Westwood) pipped me there.
"I had a great season in 2012 and was able to win with probably one of the best finishes I've had in a golf tournament, finishing with five birdies in Dubai to win the tournament and win the overall thing."
Last year McIlroy's four tournament victories - including the Open and US PGA - meant he had the title secured before the final event in Dubai, where he finished second behind Ryder Cup team-mate Henrik Stenson.
