McIlroy suffered disappointment in the inaugural event in 2009, when he led going into the final tournament but was overhauled as Lee Westwood won the Dubai World Championship to claim both titles in the emirate.
In November 2007, European Tour chief executive George O'Grady announced that the Race to Dubai would replace the Order of Merit with a prize fund of $10 million -- which was later reduced by a quarter due to the economic downturn. Getty Images
