World number one Rory McIlroy ended the year by winning the World Tour Championship in Dubai this afternoon.

The Irishman went into today's final round with a share of the lead on 17-under with Luke Donald.

The duo were challenged by Englishman Justin Rose for a while, but McIlroy claimed the title as a result of five straight birdies on the last five holes.

"Well done to @McIlroyRory! 5 birdies in a row to finish off a season that will be difficult to be bettered!!! #whataplayer #truenumber1," fellow golfer Eduardo Molinari tweeted shortly after his success.

McIlroy's success means that he will end the year top of the rankings.
