Neymar and Giovani Lo Celso scored superb late goals as Paris Saint-Germain restored its 11-point lead at the top of Ligue 1 with a 3-0 victory at Lille.
Marseille's 6-3 thumping of Metz on Saturday (AEDT) had cut PSG's advantage, but Unai Emery's men, without Kylian Mbappe because of his suspension, finished strongly to make sure of three points at Stade Pierre-Mauroy.
Yuri Berchiche scored the opener in first-half stoppage-time, the defender firing in a low drive, although Lille felt the goal should have been disallowed for an offside in the build-up.
Neymar effectively ended any hopes of a home fightback with 13 minutes to play, guiding a free-kick into the top-left corner from the edge of the penalty area for his 18th Ligue 1 goal of the season.
Yet PSG was not finished there, Lo Celso sending a glorious chip over the head of goalkeeper Mike Maignan from 20 yards to extend his team's unbeaten run against Lille to 15 games in all competitions.
PSG survived a second-half injury scare for captain Thiago Silva, ahead of their upcoming UEFA Champions League clash with Real Madrid, and the league leader has now won its past 19 league games in which it has scored first.
