Rafael Nadal will bring down the curtain on his 19-year French Open career with the likelihood of adding to his 14 titles greatly diminished before he leaves behind a record and reputation unlikely ever to be matched. The great Spaniard, a 22-time Grand Slam champion, won his first title at Roland Garros as a teenager in 2005. A week on Monday, he will celebrate his 38th birthday. A former world number one, who is now at 276 in the world, Nadal has only played 15 matches since January last year as a hip injury and then a muscle tear were added to a depressing history of physical ailments which have forced him to miss 12 Grand Slam tournaments in his career.
