Rafael Nadal returns to Grand Slam tennis and aims to move level with Roger Federer's tally of 20 major titles when an unfamiliar-looking French Open starts in Paris on Sunday.
Nadal, 34, skipped the recent US Open but is generally considered the favourite to win a record-extending 13th title at Roland Garros.
Federer is out with a knee injury but top seed Novak Djokovic and wildcard Andy Murray are in the men's draw.
In the women's singles, Serena Williams goes again for a record-equalling 24th Grand Slam title.
British number one Johanna Konta leads the nation's hopes of its first singles champion at Roland Garros since Sue Barker in 1976.
