Mbappe was at his scintillating best early. He opened the scoring inside six minutes, sitting down an Auxerre defender before lashing a shot into the top corner. He made it two shortly after, curling one past the sprawling home goalkeeper from outside the box.
The Parisians really should have been 3-0 up by half-time, but Hugo Ekitike got the ball tangled in his feet with the goal gaping.
And his blunder was enough to let Auxerre back into the contest. The home side reduced the deficit in the 51st minute, with PSG’s backline undone by a simple long ball, allowing Lassine Sinayoko to dart in behind and finish.
The home side had a smattering of opportunities to equalise, but crucial stops from Gianluigi Donnarumma saved the Parisians from another Ligue 1 embarrassment and left them on the brink of a second successive title.
