Facing the goal from the top of the 18-yard box, surrounded by three defenders, Kylian Mbappe tried the spectacular.
He pivoted to his left, spinning to one side, before attempting to turn onto the other. But for all of his rotation, he simply lost the ball, a flurry of opposition defenders converging to poke it away. PSG's star striker turned away in frustration, while Lens regained possession.
It was one of numerous aggravating moments for Mbappe, who found himself shut down by a dogged opponent. With Lionel Messi still out of the team and Neymar suspended, PSG needed their star striker to deliver. But the Ligue 1 leaders never got him in the game, while Lens were devastating on the break, stealing a 3-1 win to shrink Les Parisiens' lead atop the table to just four points.
Lens opened the scoring inside five minutes when Przemyslaw Frankowski volleyed home from close range. But PSG responded shortly after, with Hugo Ekitike latching on to a loose ball before finishing from a tight angle. Star man Lois Openda made it 2-1 for the hosts 20 minutes later, beating two defenders and squeezing the ball under Donnarumma to complete a fluid counter attack.
Lens continued to push the advantage in the second half, and found a third shortly after the break. Massadio Haidara dispossessed Fabian in front of the PSG box, before feeding Openda, who backheeled the ball into the path of Alexis Claude for an easy finish. PSG manager Christophe Galtier reacted with a series of substitutions, but with a thin bench, saw his replacements fail to offer any sort of lift to his side. And Mbappe never got in the game, leaving PSG devoid of options as they fell to a convincing away defeat.
