Justin Rose rates his season worthy of a “B-plus or A-minus” at the moment, but believes he can earn an upgrade with victory in the DP World Tour Championship and a second Race to Dubai title.

Rose is one of seven players in contention to end the season as European number one, although the former US Open champion needs to finish second or better in Dubai to have a chance of overhauling Rory McIlroy.

Even a second European Tour title of the season at Jumeirah Golf Estates would not be enough if McIlroy, who has never finished outside the top 11 in six appearances, finished alone in second.

But Rose is confident his recent victory in Hong Kong and his own course form in Dubai - he has finished second, 10th and second in the last three years - gives him the chance to claim a second money list title.

"I fancy my chances," said Rose, who finished top of the Order of Merit in 2007. "For me, it's a pretty simple equation. I need to go out and pretty much win the tournament and if I do that, it could be a great week. There's probably more pressure because I have to win, but it's a much more simple equation. Those guys (McIlroy and second-placed Danny Willett) are going to have to keep their eye on one another because there's a scenario where they could finish 20th and 25th and pick up the Race to Dubai."

Marc Warren, one of three Scots competing in the lucrative, season-ending showdown, is aiming to finish the campaign on a high as he looks to move up the world order.

The Scot is currently ranked 28th on the Race to Dubai and just two spots shy of a European Tour best finish of 26th, which he achieved a year ago.

However Warren has dropped to 66th on the World Rankings and will need to be inside the top-50 by December 31st if the 34-year old is to make a maiden Masters appearance.

“If I was to win this week or do very well, and that is always the goal, then there’s massive Race to Dubai and World Ranking points on offer so it’s a great opportunity to end my season on a big note,” he said.

Stephen Gallacher and Richie Ramsay are the other Scots in the field.
