In his first game since his suspension for his unauthorized travel to Saudi Arabia, Lionel Messi received some boos from Paris St-Germain supporters as the Ligue 1 leaders defeated Ajaccio 5-0.
After Achraf Hakimi responded after Thomas Mangani punched him, both teams finished the match with 10 players.
Hakimi and Fabian Ruiz scored goals for PSG in the opening period.
Before Mohamed Youssouf's own goal, Mbappe scored twice to start the second half, sending Ajaccio to the bottom of the league.
The best opportunity for Ajaccio came in the 67th minute when Mickael Barreto's right-footed attempt from beyond the box almost missed the crossbar.
Messi played the entire 90 minutes, making his first appearance for PSG after the club handed him a two-week suspension for traveling to Saudi Arabia without their permission.
Four points separate Christophe Galtier's PSG from a record-breaking 11th French championship.
With three more games left, they have a six-point lead over Lens, who are currently in second place.
