Nadal boasts a sensational career record at Roland Garros with 72 wins and just two defeats, against Djokovic in 2015 and an injury-affected shock loss to Robin Soderling in 2009.
Can Rafael Nadal, after two years of disappointments, finally get his 10th French Open title this season? That includes nine French Open championships, the most by any man at one major in history; Martina Navratilova won nine Wimbledon titles on the women's side.

World No. 1 Andy Murray is seeded to face 2015 champion Stan Wawrinka in the last four. "He's been in my shoes before, playing Grand Slams, being the best in the world, facing all the challenges ... we can relate to each other".
"It's tough to say that he has come all the way back to his absolute peak but he is playing tremendous tennis", seven-times major victor John McEnroe told Reuters.

"And after these three I think there are some players who can go very deep here in paris, who can make big surprises and to these players I count Sascha (Alexander Zverev) and myself", the Austrian added.More news: Trump calls foreign trip a 'home run' in remarks to US troops
