Superstars are gearing up to play at Roland Garros next week.

King of clay Rafael Nadal and world number one Serena Williams joined multiple grand slam winner Roger Federer and French Open champion Maria Sharapova.

For a mock tennis match in Paris, Nadal is an overwhelming favorite to lift the trophy for an eighth time at Roland Garros and Serena Williams is also a stand-out favorite to win a second French Open title. -- ANC Dateline Philippines, May 24, 2013
