Montpellier veteran Souleymane Camara netted a late winner as they came from behind to beat Paris St Germain 3-2 in Ligue 1 on Tuesday.
The defeat ensures that PSG, who are Ligue 1 champions, continue their stuttering end to the season.
It was a third defeat in their last four league games for PSG, who also let a two-goal lead slip in Saturday’s French Cup final before losing to Stade Rennes on penalties.
PSG, who secured the Ligue 1 title earlier this month, remain 16 points ahead of second-placed Lille despite the latest setback.
PSG and Montpellier exchanged own goals in the first half before Angel di Maria put the visitors 2-1 ahead just after the hour mark.
Yet Andy Delort equalised after a quick attack launched from the back by Montpellier with 11 minutes left before a horror defensive error allowed the hosts to steal the ball.
And 36-year-old Camara’s shot was deflected in to win the game with time running out.
Montpellier moved into fifth place, five points behind St Etienne in fourth.
