Who can win the Race to Dubai and what does McIlroy need to be No 1?

The Race to Dubai season reaches its climax this week at the DP World Tour Championship, live on Sky Sports, with nine players still in with a chance of topping the season-long standings.

Only the top 50 available players in the rankings are eligible to tee it up at Jumeirah Golf Estates in Dubai, where Eugenio Chacarra enters as Race to Dubai leader and looking to become just the third Spaniard to win the Order of Merit.
