Rory McIlroy believes he needs to win at least one of his next three events to become only the second man to win both the FedEx Cup and Race to Dubai title in the same season.
Reigning Open champion Henrik Stenson achieved this feat in 2013 and McIlroy is hoping to emulate his Ryder Cup team-mate.
The world No 3 is looking to win the Race to Dubai for a third year in a row - and fourth time in five years - but currently trails Danny Willett by more than one million points.
Willett heads the table from Stenson, with all three teeing-up at this week's WGC-HSBC Champions event in China which features 40 of the world's top 50 players.
In his chase to win both Tour order of merit titles, the 27-year-old McIlroy said: "It would be great to get the double.
"I've got three tournaments left to try to do that. I've got a lot of ground to make up as well.
"Danny has had a great season, so has Henrik, so I know what I need to do in the last three weeks.
"I probably need at least one win, hopefully two, and hopefully those boys not to play as good as they have been.
"I know I've got a lot to do but hopefully I can play well enough and at least give myself a chance."
As for his chances at Sheshan International in Shanghai, the Northern Irishman added: "I wanted to come into these weeks feeling fresh and feeling ready to go.
"I'm sure there will be a little bit of rust in there that I will need to work off but, the last few times I've played, I've played very well and there's no reason why I shouldn't be able to keep up that run of form this week and hopefully to the end of the season.
"It's my sixth time in Shanghai and I've played well here but not quite well enough to win. Hopefully I can change that this week.
"I feel like I'm playing well enough and that I've showed enough good form around this golf course in the past to be confident that I can give myself a chance this week."
