Rennes scored just before and after the break to beat Paris Saint-Germain 2-0 on Sunday and hand the runaway league leader its first defeat of the season.
Gaetan Laborde put Rennes ahead on the stroke of halftime after PSG had started to get on top, with Lionel Messi hitting the crossbar with a freekick in the 31st minute. Laborde then turned provider in the 46th for midfielder Flavien Tait. PSG had won its opening eight games but had been fortunate in some and needed injury-time goals to edge a win against Lyon and Metz.
Rennes opened the scoring on 44 minutes when Laborde converted from Kamaldeen Sulemana’s superb cross.
Tait added a second soon after the restart with a sweeping finish into the bottom corner.
After slicing an effort high over the bar in the first half, Mbappe thought he had pulled a goal back for Pochettino’s side midway through the second half, only for it to be ruled out for offside by the video assistant referee (VAR).
The Frenchman is now on a run of five games without a goal in all competitions.
PSG were spared further damage when referee Ruddy Buquet reversed his decision to award Rennes a penalty for Achraf Hakimi’s foul on Laborde after checking the pitchside monitor.
Neymar missed a volley in the first half and Idrissa Gueye fired wide of the post, but Lionel Messi came closest for PSG when he hit the crossbar from a free-kick.
Bruno Genesio’s Rennes side had only won twice in Ligue 1 heading into Sunday’s game, but were clinical in front of goal and scored from two of their four shots on target.
Mauricio Pochettino’s side did not have a single shot on target, despite Messi, Neymar and Kylian Mbappe all starting.
The defeat is PSG’s first in Ligue 1 since April, when they were beaten by last season’s eventual champions Lille.
The result leaves PSG top of Ligue 1 on 24 points, six points clear of Lens, while Rennes move up to seventh.
