Nice started brightly and caused havoc as PSG struggled to find its rhythm in the early stages.

Ali Al-Abdi soon took advantage of the visitors' lacklustre start, opening the scoring six minutes before half-time with a powerful strike from a corner.

Ousmane Dembele, who was dropped in for PSG's UEFA Champions League match last week, orchestrated its equaliser, picking out Mendes, whose deflected shot beat the keeper to hit the back of the net seven minutes after the break.

PSG almost had a second moments later, Marquinhos rising high to meet Lee Kang-in's cross, only to see his powerful header rebound off the post.

Nice held firm despite the late pressure from PSG as goalkeeper Marcin Bulka kept out good efforts by Vitinha and Dembele.

It leaves PSG two points behind leader Monaco heading into the international break.
