Reynet made six saves in total to keep his side in with a shout of nicking a point. If that is to happen, though, Nimes need to show more of an attacking threat in the second period - not easy when playing with 10 men against the champions.
PSG take a 1-0 lead into half-time against 10-man Nimes through Mbappe's coolly-taken goal on the counter. Landre was earlier dismissed for the hosts for a strong challenge on Thiago, who set up Mbappe for that opener. Tuchel's men would have been out of sight at the midway point if not for some superb saves from Reynet.
45' + 3' HALF-TIME: NIMES 0-1 PARIS SAINT-GERMAIN
45' + 2' Mbappe gets away from one opponent and cuts the ball back towards the penalty area, where a Nimes player is waiting to clear it away.
45' + 1' Three minutes have been added on at the end of a lively first half.
45' Arpinon has Reynet to thank for this game not being out of his side's reach just yet. PSG still have a couple of minutes to find a second goal before half-time.
43' NEARLY! PSG are really racking up the shots on target now. Mbappe heads downward from the edge of the six-yard box and Reynet uses his legs to keep it out. The visitors should be out of sight.
41' ANOTHER SAVE! Reynet is this time equal to Gueye's headed effort from the corner. There is another stoppage in play following Bakker's strong challenge on Fomba, which goes unpunished.
39' REYNET DENIES KEAN! The new PSG signing gets lucky with a deflection into his path and has just Reynet to beat. He looks to find the bottom-left corner but the Nimes stopper makes yet another great save.
37' SHOT! Eliasson plays a quick give and go outside the box and bends a fairly weak effort down the middle for Navas to gather.
36' SAVE! If nothing else, that Mbappe goal has quietened the home crowd down a little. Florenzi is a long way out but decides to pull the trigger, forcing Reynet into another half-decent save down to his right.
34' It could be a long day for Nimes now that PSG have found a way through. If the home side want anything from this game, they will have to attack at some point.
31' WHAT A SAVE! This is an incredible stop from Reynet. Florenzi sends in another good delivery from the right and Herrera gets plenty of power behind his header, but the Nimes goalkeeper gets a strong left hand to the ball.
29' It has been an incredibly stop-start game so far, with both teams guilty of committing fouls galore - Kean the latest player to be clattered. Nimes are down to 10 men but are more than holding their own for now.
27' A great sliding challenge from Burner on Bakker halts the PSG full-back's charge into the box.
26' CHANCE! The first real opportunity of the match falls the way of Mbappe. He gets on the end of Sarabia's right-sided cross and sends a header spinning wide of the target from six yards out.
24' Burner is given a final warning by busy referee Clement Turpin for barging straight into Mbappe, with no real intention of winning the ball.
23' Paris Saint-Germain have lost only two of their last 15 away games in Ligue 1 (W12 D1), after losing five of their previous six (W1). They have scored two goals or more in 11 of them.
21' Gueye is perhaps lucky not to have been issued a red - that was a really bad tackle on Deaux. PSG's players need to keep their cool.
16' This game certainly had an edge to it, with plenty of challenges flying in early on. PSG have not really been able to find any sort of rhythm to their game as a result of the stoppages.
14' PSG felt Deaux should have been sent off early on... well they have their wish this time as the referee had no hesitation in showing Landre a red for that challenge on Rafinha. A tough task for the hosts has just become a whole lot tougher.
11' Paredes has gone back down. He has been unable to shake off the injury sustained in a challenge from Deaux and will likely have to make way.
10' Mbappe charges down the left and sends a cross into the middle towards new team-mate Kean. Miguel puts the striker under enough pressure to make it a difficult chance, which ends with the first-time shot spinning over the crossbar.
8' Paredes stayed down following that challenge from Deaux, which PSG's players feel was worth more than just a yellow card. After a bit of treatment, the midfielder is back on.
5' Nimes' players are working incredibly hard for every ball. They turn over possession and a cross comes on from the right, but Kimpembe gets his head to it first.
4' SAVE! Paredes plays in Sarabia with a nice pass. The ball is worked across to the other side and Mbappe cuts inside, curls a shot on target and is denied by a routine Reynet save - possibly his first of many.
2' SHOTS! It has been a bright start for the home side. Eliasson gets a shot away within 15 seconds, which Navas watches sail over the bar, before Paquiez sends an effort flying over from further out.
1' KICK-OFF! PSG get us under way! Following Rennes' 1-1 draw with Dijon a little earlier, the visitors can move to the top of Ligue 1 with a victory here.
Both sets of players have made their way onto the field and kick-off is now just a few minutes away at the Stade des Costieres.
Nimes have lost their last three home games against Paris Saint-Germain in Ligue 1, after losing only one of their first nine (W7 D1). Today's hosts have also failed to score in six of their last eight top-flight meetings with PSG, conceding 16 goals during that run.
PSG are without a number of first-team regulars today - Neymar, Angel Di Maria, Layvin Kurzawa, Thilo Kehrer, Mauro Icardi and Juan Bernat among them - due to injuries, suspensions, fitness concerns and coronavirus restrictions. Tuchel has made five changes from the 6-1 win over Angers, with Rafinha and Kean being handed their debuts.
Nimes have made four changes from their 1-0 win over Montpellier a little under two weeks ago. Two of those are enforced as Antony Briancon and Zinedine Ferhat miss out through suspension and injury respectively, while Meling and Denkey drop down to the bench. Miguel, Paquiez, Roux and Eliasson return to the XI.
Subs: Timothee Pembele, Xavi Simons, Sergio Rico, Bandiougou Fadiga, Colin Dagba, Ander Herrera, Maxen Kapo, Jese, Kays Ruiz-Atil.
PSG XI (4-3-3): Keylor Navas; Alessandro Florenzi, Abdou Diallo, Presnel Kimpembe (c), Mitchel Bakker; Idrissa Gueye, Leandro Paredes, Rafinha; Pablo Sarabia, Moise Kean, Kylian Mbappe.
Subs: Karim Aribi, Matteo Ahlinvi, Moussa Kone, Pablo Martinez, Sofiane Alakouch, Birger Meling, Marco Majouga, Lucas Dias, Kevin Denkey.
NIMES XI (4-3-3): Baptiste Reynet; Patrick Burner, Florian Miguel, Loick Landre, Gaetan Paquiez; Lamine Fomba, Adrian Cubas, Lucas Deaux; Renaud Ripart (c), Nolan Roux, Niclas Eliasson.
PSG made a poor start to their latest title defence, losing their opening two games to Lens and Marseille, albeit with a depleted squad. Since then, however, Thomas Tuchel's men have won four games on the spin and conceded just once, most recently thumping Angers 6-1.
Nimes have made a mixed start to the 2020-21 campaign, winning two, drawing two and losing two of their opening six matches. Jerome Arpinon's side picked up a 1-0 win away at Montpellier last time out to make it three without defeat as they moved into 13th place.
