Nadal is attempting to win an unprecedented tenth title in Paris, while victory for Djokovic would see the Serbian become just the third man in history - after the great Australians Roy Emerson and Rod Laver - to win each of the Grand Slams on more than one ocassion.
Djokovic and Nadal posted identical scorelines, with the defending champion seeing off Joao Sousa 6-1 6-4 6-3 before Nadal defeated Robin Haase. Nadal, whose next challenge will be against Nikoloz Basilashvili of Georgia, believes things are pretty much under control.
Johnson will next face sixth-seeded Dominic Thiem, who moved into the third round with a 7-5, 6-1, 6-3 win over Simone Bolelli of Italy.
Tsonga managed to save three match points, but the 91st-ranked Olivo converted the next one with a forehand cross-court victor to win 6-4 and advance to the second round. Now Nadal has turned for his support and ideas from another Mallorcan, fellow French Open champion, fellow former No1, Carlos Moya.
"What I'm interested in is the future, and I hope I'll play better in the next tournaments and pick up a couple of trophies, because there is still a lot to be done out there". "Agassi solved hard situations on the court when he was a player", said Moya. "He's waiting for me for a serious talk", joked the 30-year-old after seeing off Granollers for the fourth time.
He said: "For the moment, I am fine". "I go for walks from my hotel, I walked from Montmartre to Notre Dame". In addition to the Serbian, the bottom half of the draw also counts with extremely risky players such as Dominic Thiem, David Goffin, Grigor Dimitrov or even Milos Raonic.
It was the first time Tsonga has lost to a player ranked as low as No. 91 at a Grand Slam. But such a scare never looked likely at the Spaniard's home from home at Roland Garros. "So it was really late", Olivo said.
"As I told you, fitness-wise and physically, I was exhausted".
"I'm very happy to come back on the Court Philippe Chatrier", said Nadal, who finished with 33 winners to 13 unforced errors, breaking Haase five times.
The 2016 Wimbledon finalist Milos Raonic began his French Open very impressively with a straight sets win over Steve Darcis, although he had to battle back from a set down in his second round match against Rogério Dutra Silva, eventually prevailing 4-6 6-2 6-3 6-4. "That's my goal, really, every match", Williams, who plays Japan's Kurumi Nara.
Reigning champion Djokovic teamed up with 1999 champion Agassi in a dream-team player-coach combination just before the start of the tournament.
