Paris Saint-Germain have won their fifth straight Ligue 1 title after beating Lens 2-0 in a top-of-the-table clash at the Parc des Princes on Wednesday.
PSG needed only a draw to seal a fifth consecutive Ligue 1 crown and are now nine points ahead of Lens with one game left.

Georgia winger Khvicha Kvaratskhelia continued his red-hot form to open the scoring in the 29th minute before Ibrahim Mbaye struck in second-half stoppage time to ensure the title remained in the French capital.
"Without a doubt this was difficult, Lens did so well this season," PSG coach Luis Enrique said. "I think they deserved more tonight but [goalkeeper Matvei] Safonov was incredible tonight."
Luis Enrique has guided PSG to a record-extending 14th domestic title, the third under his tenure since arriving in 2023. PSG have a chance to secure a treble this season, having already won the league and French Super Cup.
Wednesday's match was rescheduled from April 11 by the French league to help titleholder PSG's ambitions in the Champions League. PSG takes on Premier League leader Arsenal in the Champions League final on May 30 in Budapest.
Although the postponement was strongly contested by Lens, coach Pierre Sage's side had no say in the matter.
Lens also have a final to prepare for -- against Nice in the French Cup on May 22 -- and Sage left his two best forwards -- wingers Florian Thauvin and Allan Saint-Maximin -- on the bench against PSG until the hour mark.
PSG punished a Lens error when forward Ousmane Dembélé intercepted a sloppy pass from defender Malang Sarr and fed Kvaratskhelia, who scored with a clinical finish.
PSG scored in stoppage time through Mbaye, the 18-year-old forward who thumped a pass from Désiré Doué in off the crossbar moments after Lens had fluffed yet another chance.
Lens should already have been level -- or even ahead -- at the break but striker Wesley Saïd misjudged a close-range header and then shot straight at goalkeeper Safonov in first-half stoppage time.
Safonov kept out another effort from Abdallah Sima early in the second half when the striker went clean through. Sima then hit the post after collecting a superb pass from Thauvin in the 74th.
"I had some luck today," Safonov acknowledged. "If my opponents had put their shots a bit more either side of me it would have been different."
Saint-Maximin was dangerous when he came on in the second half but wasted several good situations when excessively trying to put himself in the perfect shooting position.
The last team to stop PSG winning the title was Lille in 2021. This season was closer than the last, however, when PSG sealed the title without losing and with six games left.
