Wawrinka and Williams celebrate in Paris

After a compelling French Open tournament, it was Serena Williams and Stan Wawrinka who eventually came out on top.

Stan Wawrinka was the surprise winner of the men's competition, while Serena Williams picked up another Grand Slam after a typically-dominant display from the American.

Following Novak Djokovic's comprehensive defeat of nine-time French Open champion Rafael Nadal in this year's quarter-finals, the stage appeared set for the world number one to land the one Grand Slam to have so far eluded him.

It seemed even more certain that Djokovic would finally win in Paris after beating Andy Murray in a five-set semi-final and then going a set up in the final against Wawrinka.

However, the Swiss eighth seed then produced three of the best sets of tennis of his life to win the final, claim his second Grand Slam title and deny the Serb the chance of becoming only the eighth player to have won all four majors.

Wawrinka showed impressive form throughout the tournament. He dropped just one set on the way to the quarter-finals where he beat Kei Nishikori, despite the Japanese player recovering from two sets down to force a decider. In the semi-finals, Wawrinka met local favourite Jo-Wilfried Tsonga and he came through in four sets to reach his second Grand Slam final after winning the Australian Open last year.

His French Open triumph ensures that Wawrinka will climb up the world rankings and he will go into the final two Grand Slams of the season, Wimbledon and the US Open, hoping to exceed his best finishes there; the quarter-finals and semi-finals respectively.

This year's French Open was also notable for Nadal's defeat; only his second ever on the clay of Paris. He beat Djokovic in last year's final but this time he was well beaten by the Serb and it remains to be seen whether he can recover to become once again the 'King of Clay'.

Murray had an encouraging tournament, though he again lost to Djokovic - his eighth straight loss to the world number one. However, Murray did reach the semi-finals in Paris and came from two sets down to force the match with Djokovic into a deciding fifth.

In the women's game, Serena again confounded the doubters to win yet another major title.

Beating Lucie Safarova in the final, she claimed her third French Open and the 20th Grand Slam singles title of her long career.

With Wimbledon and the US Open following in the next few months, the American has Steffi Graf's 22 titles, a record in the post-Open era, in her sights and she is still the woman to beat.

Her victory over her Czech opponent in the Paris final demonstrated why she remains world number one in the WTA rankings and will be favourite going into the grass court season and Wimbledon.

She suffered illness in the latter stages of the French Open; struggled to beat Timea Bacsinszky in the semi-finals and lost the second set to Safarova in the final. Her Czech opponent then went an early break up in the third to lead 2-0, but Williams demonstrated her reliance, winning the next six matches in a row to win the match and the title.

Her immediate rivals in the world rankings had a disappointing tournament. Maria Sharapova, second seed, reached the fourth round before losing to eventual finalist Safarova.

Last year's beaten finalist Simona Halep made a second round exit, beaten by Mirjana Lucic-Baroni and Eugenie Bouchard, who reached last year's Wimbledon final, continued her poor form in 2015, going out in the first round after a straight-sets defeat to Kristina Mladenovic.

In the world's top 10, apart from Williams, only Ana Ivanovic reached the latter stages of the tournament. She made the semi-finals before losing to Safarova in straight sets.
