Neymar marked his return to the Paris St-Germain team with two goals and two assists as the Ligue 1 leaders swept aside Rennes.
The forward was suspended for last weekend’s win over Lille and missed the midweek League Cup win at Strasbourg to travel to Brazil for personal reasons.
He struck after four minutes before setting up Kylian Mbappe to score.
Firmin Mubele got one back but Edinson Cavani fired in from a through ball by Neymar, who then poked in a fourth.
Both sides had a player sent off with Benjamin Andre receiving a second yellow card in the second half for the hosts while PSG centre-back Presnel Kimpembe was dismissed for a foul inside the box late on.
Midfielder Wahbi Khazri, on loan from Sunderland, then fired over the bar from the penalty.
PSG are nine points clear of Monaco at the top of the table with 47 points from 18 games.
Rennes, meanwhile, remain sixth on 25 points.
