Ousmane Dembele is Ligue 1's top scorer with 18 goals
Paris St-Germain comfortably beat Lille to extend their unbeaten run to 22 games going into Wednesday's Champions League tie with Liverpool.
Luis Enrique's PSG are 16 points clear of second-placed Marseille and 10 league games from the first unbeaten Ligue 1 campaign.
They led when Bradley Barcola scored from the rebound after Ousmane Dembele's shot was saved.
Marquinhos headed in Desire Doue's corner for his first PSG goal since December 2022.
And free-scoring Dembele swept in their third to cap off a slick passing move. The France winger has scored 20 in his past 14 games.
Doue blasted a shot into the top corner from Dembele's pass to make it 4-0 after 37 minutes.
The champions eased up after that - with Jonathan David pulling one back late on after Gianluigi Donnarumma parried a shot from former PSG player Ethan Mbappe.
PSG, who have won their past 10 games, host Premier League leaders Liverpool in their Champions League last-16 first leg tie on 5 March (20:00 GMT).
