Luke Donald hoping to roll back the years at Wentworth

Former world number one Luke Donald hopes being back at the scene of some of his biggest triumphs will kick-start his season and halt a worrying slide down the rankings.

Donald first reached top spot by beating Lee Westwood in a play-off for the BMW PGA Championship in 2011, the year he became the first player to top the money list on both sides of the Atlantic in the same season.
