The 18-year-old pounced early on to score his fifth goal in 14 games in all competitions so far this season.
Dani Alves was given far too much space out wide and he picked out the perfect cross for the French international, who made no mistake from eight yards.
The goal marked a great start to the game for PSG, who were looking to maintain their four-point lead at the top of Ligue 1 following their Champions League exploits in midweek.
