Monaco set a clean sheet record with victory over Lille, while Montpellier were Saturday's big winners in Ligue 1.
Monaco's miserly defence set a club record in recording a 1-0 win at Lille in Ligue 1.
Dimitar Berbatov headed the only goal of the game after 57 minutes, extending Monaco's unbeaten run to seven league matches, with the seven consecutive clean sheets chalked-up during that time standing as a club best.
Leonardo Jardim's team lie fifth in the table, six points behind leaders Lyon and one place ahead of Montpellier - Saturday's big winners as they thumped Nantes 4-0 at the Stade de la Mosson.
Paul Lasne's mishit cross gave Montpellier a fortuitous eighth-minute lead and they put Nantes to the sword after half-time.
Lucas Barrios set up Kevin Berigaud for his third goal of the season in the 57th minute and the on-loan Spartak Moscow striker completed the scoring with his sixth goal in five Ligue 1 matches after Anthony Mounier netted.
Lorient are precariously placed three places and as many points above the relegation zone after coming out on the wrong side of a 3-2 thriller at Guingamp.
Claudio Beauvue opened the scoring for Guingamp and Christophe doubled their advantage in the 69th minute.
Benjamin Jeannot had reduced the arrears from the penalty spot by the time Beauvue completed his brace and, despite being reduced to 10 men following a second yellow card for Younousse Sankhare, Lorient closed the gap again in stoppage time through Dorian Leveque's own goal.
Elsewhere, Bastia extended their unbeaten run to five league games by holding visitors Bordeaux to a goalless draw.
