Nadal is chasing a 10th title at Roland Garros while second seed Djokovic, working with new coach Andre Agassi, is looking to defend the only major he still holds.

World number one Andy Murray is seeded to face 2015 champion Stan Wawrinka in the last four.

Murray starts against Russia's Andrey Kuznetsov, Djokovic tackles Spanish clay courter Marcel Granollers while Nadal meets combustible Frenchman Benoit Paire.

If the seedings work out, 2016 runner-up Murray, who is reportedly suffering from an illness, would face Japan's Kei Nishikori in the last eight.

The other quarter-finals would see Wawrinka meet 2014 US Open champion Marin Cilic, Nadal would meet Canada's Milos Raonic while Djokovic could take on Dominic Thiem.

Djokovic demolished highly-regarded Austrian Thiem for the loss of just one game in the Rome Masters semi-finals last week.

The 30-year-old Nadal has already reached the magical 10 titles number this year at the claycourt events in Monte Carlo and Barcelona.

For good measure, he also won Madrid for a fifth time, ending a seven-match losing streak, stretching back over two years against Djokovic in the process.
Nadal boasts a sensational career record at Roland Garros -- 72 wins and just two defeats, to Djokovic in 2015 and an injury-affected shock loss to Robin Soderling in 2009.
                  
'no magic pattern'             
                  
On clay this year, Djokovic has been on an upward curve -- quarter-finals in Monte Carlo, semi-finals in Madrid and a runners-up spot in Rome where he was comprehensively demolished by Alexander Zverev.

"It was one of my last dreams in terms of tournaments that I wanted to win here," said Djokovic at the draw on Friday.

"It was missing from my list so I ticked it off and got the full set of Grand Slams."
"Looking at the trophy again brings back lots of memories. It was one of my most special feelings."

Murray has endured a wretched season by his standards with an elbow injury not helping his cause.

He lost in the third round in Monte Carlo, made the semis in Barcelona, was a third-round loser in Madrid before an opening defeat in Rome to Fabio Fognini.

In the women's draw, top seed Angelique Kerber starts against experienced Russian Ekaterina Makarova in the first round.

Kerber is due to face defending champion Garbine Muguruza of Spain in the semi-finals.

"I am super-excited to be here. I am preparing the best I can but there is no magic pattern," said Muguruza who comes into the tournament having suffered a neck injury in Rome last week.

Muguruza has a tough opener against former champion Francesca Schiavone.

Second seed Karolina Plisova was drawn to face 2014 runner-up Simona Halep in the semi-finals but will start against Zheng Saisai of China.

Halep has an ankle injury and described her chances of making Roland Garros as "50-50" earlier this week.

The women's event is regarded as being wide open with Serena Williams, Maria Sharapova and Victoria Azarenka al absent.
If the seedings works out, Kerber will face former champion Svetlana Kuznetsova in the last eight with Muguruza against Dominika Cibulkova.

Elina Svitolina would face Halep, who she defeated in the Rome final, while Britain's Johanna Konta would be Pliskova's last-eight rival.
