Messi was booed by home fans after PSG defeated Ajaccio.
Lionel Messi was booed by some Paris St-Germain fans as the Ligue 1 leaders defeated Ajaccio 5-0 in his first match since being suspended for his unauthorised travel to Saudi Arabia.
After Thomas Mangani punched Achraf Hakimi, who reacted, both teams were down to ten players.
PSG’s Fabian Ruiz and Hakimi scored in the first half.
Mbappe scored twice in the second half before Mohamed Youssouf’s own goal sent Ajaccio down.
Mickael Barreto’s right-footed drive from outside the box just went over the bar in the 67th minute, Ajaccio’s finest chance.
Messi played the whole 90-minute game for PSG, his first appearance after the club suspended him for two weeks for traveling to Saudi Arabia without authorization.
PSG, led by Christophe Galtier, is four points away from a record 11th French crown.
With three games remaining, they are six points ahead of second-placed Lens.
