Paris St-Germain suffered their first defeat since March, falling to in-form Lens in Ligue 1.
Second-placed In 17 Ligue 1 games this season, Lens have only suffered one defeat and are currently only four points behind Christophe Galtier’s all-star-studded league leaders.
For Franck Haise’s team, Lois Openda scored one goal and assisted on another.
Lionel Messi, who is still recovering from the World Cup, and Neymar, who was suspended after receiving a red card on Wednesday, were both absent for PSG.
Przemyslaw Frankowski gave the hosts the lead after five minutes when he volleyed into an open goal off Gianluigi Donnarumma of Italy.
Hugo Ekitike soon restored PSG’s advantage, but Openda gave Lens the lead once more in the 28th minute by eluding defender Marquinhos and firing past Donnarumma into the bottom corner.
Despite Kylian Mbappe playing the entire game, Alexis Claude-Maurice added a third two minutes into the second half, and the team from northern France managed to hold on for a significant victory.
On their first game back after the World Cup, Lens drew with Nice last week, but since then, they’ve won six of their past eight league games and all nine of their home games this year.
PSG’s most recent defeat was a 3-0 loss to Monaco on March 20, just ten days after losing to Real Madrid in the Champions League.
