Ousmane Dembele scored twice as Paris St-Germain came from a goal behind to beat Brest and continue their perfect start to the Ligue 1 season.
Brest took a shock lead against the champions when Romain del Castillo converted from the penalty spot after Nuno Mendes fouled Ludovic Ajorque in the area.
But Dembele, who tormented Brest throughout on the right wing, ensured the teams were level going into the break by nodding home Marco Asensio's cross.
Two goals in two minutes in the second half then proved the difference for PSG, with Fabian Ruiz putting the hosts ahead with a superb strike from distance which he rifled into the top corner.
Dembele then doubled their advantage a minute later, following up after Randal Kolo Muani had an effort blocked.
The result leaves PSG - who have won all four of their games so far - sitting two points clear of Marseille and Monaco at the top of Ligue 1.
Marseille beat Nice 2-0 and Monaco won 3-0 against Auxerre earlier on Saturday.
