Neymar scored his eighth goal of the campaign on Saturday, and he's netted in all but one of PSG's seven Ligue 1 matches. He also has six assists this term. There are few players in Europe in as good of form as the Brazilian - a trend made more impressive by the transfer speculation he endured during the summer transfer window.
The reigning champions were rarely in danger against Brest, but Neymar, Lionel Messi and goalkeeper Gianluigi Donnarumma stepped up to the plate when they were called upon.
Neymar and Messi combined beautifully for large parts of the game while Donnarumma was vital.
Galtier will be happy with another effective display from his side, especially in the wake of their Champions League win against Juventus in midweek.
He will hope, however, that a rare down game from Mbappe was just a blip.
