Nigerian youngster, Victor Osimhen has now scored five goals in as many games in his maiden season in the French top flight, putting him joint as the league’s top scorer with Lyon’s Moussa Dembele.
Lille were 2-1 victors thanks to Osimhen’s goal just before half time.
Osimhen, who scored doubles in previous home victories over Saint-Etienne and Nantes, took advantage of a dreadful error by visiting goalkeeper Ludovic Butelle to grab his goal.
Lille next travel to Amsterdam to face Ajax in their Champions League opener on Tuesday.
“If we play the same way at the end of the game when we were leading 2-0 against Ajax on Tuesday, then we will lose the match,” said coach Christophe Galtier.
“No (heads weren’t turning to Amsterdam). Now, yes… It will take a great determination, a great desire to do something because it will be very difficult.”
Lille are now third in the fledgling table, level on points with leaders PSG and second-placed Rennes.
