That's it from me tonight. Until the next time, adieu!
The win keeps PSG top of the table, five points ahead of Lille, who play Brest on Sunday. Rennes stay third but they're now six points behind the leaders.
A below-strength PSG grab an important win, thanks to three moments of excellence from Di Maria. He won the ball and set up Kean to fire in the opener, before scoring two lovely goals of his own - a dinked effort over the keeper in the first half and an accurate strike from range in the second. There's yet more injury concern for the hosts, though, with Kehrer and Gueye both going off injured, and Kean stumbling off with a bit of a limp too.
FULL-TIME: PSG 3-0 RENNES
Hunou picks up a loose ball in the area and looks to cross from the right, but Diallo clears. Navas makes a decent low save from the resulting corner.
Guirassy goes down in the area as he challenges with Diallo for a high cross, but the referee isn't interested. Goal kick.
Three minutes of stoppage time at the end of the game.
PSG are winding down the clock now.
Kurzawa is booked for a late challenge on Del Castillo. He ended up treading right on the substitute's foot, but it was clumsy rather than malicious.
The corner is met by Marquinhos, but his header down into the ground bounces straight into Gomis' gloves.
Rafinha chops onto his left foot at the edge of the area and curls towards the far top corner, and Gomis makes a strong save. Corner.
Di Maria's second goal tonight means he goes ahead of Safet Susic as PSG's eighth highest scorer ever. He has 86 goals in Parisian blue.
Grenier aims his free-kick towards the far post but no Rennes player can get a touch on it and Navas punches clear.
Guirassy gets to a loose ball just ahead of Marquinhos and wins a foul, just - just - outside the penalty area. Right on the line at the left side of the box.
Into the final 10 minutes now. Can the visitors make this interesting?
Change number four for Rennes. Del Castillo comes on for Doku, who has been a semi-regular threat but not able to find a way through.
Kurzawa heads Traore's latest cross from the right clear, but the whistle goes for an offside anyway.
Rennes should score. A loose ball breaks for Hunou just outside the area, and he lays it off to Guirassy to his left. One-on-one with Navas, he looks to curl one with his right foot, but hits it straight at the keeper. He should have put it away, and Hunou might have been better off taking the shot on anyway.
Rennes had been unbeaten in their last five away games in Ligue 1 before tonight's match. That little run will be coming to an end.
GOAL! 3-0, that'll do it! Once again it's Di Maria out of nowhere - this has been his game. Marquinhos and Dagba combine to win the ball on the right and as the Rennes defence stops to claim a foul, Di Maria picks it up, drifts toward the edge of the area and fires a left-footed effort across goal and into the bottom-left corner.
There's a bit of pinball at the edge of the PSG box but the space just won't open up for Rennes to get a shot away. It's half-cleared but comes back to Terrier, who lashes over from range.
Traore crosses from the right, and it bounces off both Danilo and Paredes before going behind for a corner. Rennes think it hit both players on the arm, and it looks close on both counts - but the VAR isn't interested.
The visitors make their third change of the night, introducing Hunou in place of Bourigeaud.
PSG aren't being very adventurous in their possession now, but they are keeping hold of the ball better - which has killed the momentum Rennes were building up. They will be happy with 2-0.
Rafinha and Dagba are the players accompanying Di Maria in attack now. It's not the most fearsome front three you'll ever see, as good as Di Maria has been.
Kean doesn't appear to be receiving any treatment now he's sat on the bench. Perhaps it was just a funny walk.
Well, here's another thing that PSG absolutely do not need. Kean is off, and walking very stiffly. Danilo replaces him.
Rennes are applying some pressure now. PSG have been camped at the edge of their own area for most of second half so far.
Grenier tees up Bourigeaud for a first-time shot at the edge of the D, but he curls high over the crossbar.
Truffert plays the ball to the feet of Guirassy in the area with his back to goal. He swivels but doesn't have time to get a shot away before it's cleared.
And then Grenier replaces Lea Siliki.
Changes for Rennes. First, Terrier replaces Gboho.
Doku gets into the area but Kurzawa and Marquinhos combine well to tackle him cleanly.
Kurzawa cuts inside from the right and tries his luck from, oh, about 60 yards out. The ball bounces twice before reaching the untroubled gloves of Gomis.
Bakker works himself a yard of space by the touchline on the left, but his cross is aimless and floats out for a throw-in on the other side.
Marquinhos tackles Bourigeaud at the edge of the PSG area and gets a break as the ball bounces off the Rennes player and out for a goal kick.
PSG haven't looked so good that Rennes won't fancy their chances of coming back into this game, but they need to find more of a cutting edge in the final third. They haven't really threatened Navas' goal in the first 45.
Gboho gets into the PSG area from the right and looks to pull the ball back from the byline, but he has too much momentum and runs it out of play.
It hasn't been a great game, but two moments from Di Maria have put PSG in control. He won the ball deep in the Rennes half and set up Kean for an excellent finish, before chipping a lovely effort of his own over Gomis to double the lead. Worryingly for the home side, Gueye and Kehrer have both had to go off injured.
Dagba is booked for pushing over Doku as the Rennes winger got away from him down the left. He has been a pest tonight.
HALF-TIME: PSG 2-0 RENNES
Rennes win an early free-kick on the left. Bourigeaud puts in a good delivery to the far post where Aguerd nods it back into the danger area, but Diallo is there to clear behind for a corner.
Di Maria's first-half goal has taken him up to eighth in PSG's all-time top scorers list. He's now level with Safet Susic on 85 goals.
Guirassy gets into the area after Doku robs Paredes but, seemingly an age later, the referee blows for a free-kick. The Rennes bench are furious about it.
Three minutes of stoppage time.
We're back underway.
A change at the break for PSG. Dagba replaces Florenzi.
Guirassy finds Gboho about eight yards out, but he's totally surrounded by PSG defenders. He holds onto the ball, waiting for an option before swivelling to shoot, but it's straight at Navas.
Kean gets ahead of his man as the resulting free-kick is swung in from the left by Di Maria, but he heads over.
Di Maria goes down in a heap after a slight touch from Traore. As much as 'attacking players pretending to be gravely wounded' is a part of the game now, Tuchel could probably do without the worry given the state of his squad right now. Thankfully for him, Di Maria gets straight back up.
Rafinha puts in a heavy tackle on Lea Siliki by the left corner flag, but it's a good challenge as he gets the ball and wins a throw-in.
Gomis almost gets himself into a spot of bother as he rushes out. Kean and Aguerd are chasing down a pass over the top but the keeper just gets there in time to hammer the ball out for a throw-in.
Traore and Doku combine again. The right-back again finds himself in space on the right and this time opts to cross from deep, picking out the run of Doku well at the far corner of the six-yard box. He goes for a side-footed volley but can't keep it down.
Another enforced change for PSG. Their medical room is going to be the busiest room in France at this rate. Kehrer went down off the ball after that shot from Doku, and he's replaced by Bakker.
Traore gets into space on the right. He pulls the ball back to Doku, wide open at the edge of the area, but he leans back as he shoots and hits his first-time effort high over the crossbar.
Lea Siliki turns inside Rafinha at the edge of the area and fires a shot at goal, but it's straight into another PSG defender in a crowded penalty area.
Bourigeaud sends a free-kick from just outside the centre-circle into the PSG box, and Marquinhos does well to stoop down and head it clear as it dips in front of him.
A lovely move doesn't get the end it deserves. Di Maria finds Florenzi with a beautiful floated cross-field pass, and he backheels it into the path of Herrera on the overlap on the right - but his cross is easily caught by Gomis.
Kean almost latches onto a ball in behind but it holds up in the pitch. He and Da Silva grapple with each other as they try to reach it, and the free-kick goes the way of the defender. It looked pretty even.
Close! Nzonzi meets the corner at the near corner of the six-yard box and flicks a header towards the back post, but it bounces just wide.
The corner is headed out as far as Lea Siliki who goes for goal with a left-footed volley. It deflects off a PSG defender and behind for another corner on the same side.
Di Maria's corner from the left is way too deep and Rennes counter through Doku. He finds Truffert on the left who looks to pick out Doku again with a cross, but it's bundled behind for a corner - this time on the Rennes left.
Di Maria has shown his worth tonight. He can be outshone by some of the bigger names at the club, but he's come up big in an important game here.
Bourigeaud fires in a decent cross along the line of the six-yard box which Nzonzi meets, but he gets under it and the ball flies over.
Rafinha fouls Gboho at the right side of the area, and Rennes have a good chance to whip in a free-kick.
Herrera gets the assist this time, a nicely weighted pass in behind.
GOAL! It's 2-0, Di Maria this time! Herrera puts him through on goal down the left channel, and he lobs a delightful effort over goalkeeper Gomis. Lovely finish from a player who has started this match very well.
Paredes tries his luck from range, but drags a right-footed effort wide to the left of goal.
There is not a lot of action in this game so far. PSG a long way short of their best, shorn of their biggest stars.
Five goals in seven appearances for Kean this season. Quite the return to form after his struggles in the Premier League.
There has been nothing in this game so far, save those little moments from Di Maria and Kean. Often, for PSG, that's all they need.
PSG are forced into an early change. Rafinha comes on for Gueye, who walks gingerly straight down the tunnel. Looks like it happened off the ball.
GOAL! Out of nowhere, PSG take the lead, it's Kean! Di Maria intercepts a loose ball from Lea Siliki just outside the area. It drops to Kean who looks to hesitate for a second, but he picks out a perfect finish, rifling the ball across the goalkeeper and into the bottom-left corner from the edge of the area.
Di Maria gets the assist for some good awareness as Lea Siliki dawdled on the ball.
Kean takes the ball off the toe of a team-mate just outside the area and looks to bustle through the Rennes defence, but it's hooked clear.
Di Maria looks to spark a counter down the left, but Gboho pulls him back and concedes a free-kick.
It looks like there's going to be a lot of onus on Di Maria to provide a creative spark for PSG tonight. If Rennes can keep him out of the game, they'll stand a good chance.
Herrera gets an early yellow for a late sliding challenge on Da Silva.
Both teams look comfortable in possession, as you would expect. PSG (64.4%) and Rennes (61.1%) are the two teams with the highest possession ratio in Ligue 1 this season.
Not a lot of action in the first couple of minutes, both teams taking the opportunity to put their foot on the ball and play it around.
The teams are on their way out onto the pitch, and we’re almost ready for kick-off.
Since QSI took over at PSG in 2011, Rennes are the only side to beat them more than once at the Parc des Princes in Ligue 1. PSG have only lost nine home league games since then, and three of them were against today’s opponents.
There’s still no Neymar, Kylian Mbappe or Mauro Icardi for the hosts, but Paredes returns. Di Maria got a goal in midweek but missed a crucial penalty, so he’ll be looking to make amends tonight. Eduardo Camavinga and Daniele Rugani are among the absentees for Rennes.
SUBS: Flavien Tair, Romain Salin, Martin Terrier, Dalbert, Gerzino Nyamsi, Lorenz Assignon, Adrien Hunou, Clement Grenier, Romain Del Castillo.
RENNES (4-1-4-1): Alfred Gomis; Adrien Truffert, Nayef Aguerd, Damien Da Silva, Hamari Traore; Steven Nzonzi; Jeremy Doku, Benjamin Bourigeaud, James Lea Siliki, Yann Gboho; Serhou Guirassy.
