Montpellier moved level with Bordeaux at the top of the table after a narrow 1-0 victory over bottom side Grenoble. Victor Hugo Montano scored the only goal of the game after 28 minutes as Rene Girard's side picked up their 15th win of the season. However, they could not find any further goals against a Grenoble side 13 points from safety.
Lille kept up their pursuit of the top two with a 3-1 victory over Boulogne with all the goals coming in the first half. The hosts were 2-0 up after 11 minutes thanks to goals by Ludovic Obraniak and Adil Rami before Olubayo Adefemi pulled one back after 28 minutes.
Obraniak scored his second of the game shortly before half-time to wrap up victory as Lille remain third and Boulogne stay second bottom, seven points from safety. Lyon are fourth after a 1-0 win over Lens, Cesar Delgado scoring the only goal with a quarter of an hour remaining.
Mistake favours Marseille
An 89th-minute own goal allowed Marseille to stay in touch with the leaders as they beat in-form Monaco at Stade Louis II. Monaco defender Nicolas Nkoulou unwittingly turned in Mathieu Valbuena's late shot to hand Marseille a victory that moved them six points behind Bordeaux.
The visitors had gone ahead after 37 minutes when their leading scorer Mamadou Niang converted from the penalty spot only for Moussa Maazou to cancel out the goal three minutes later.
Filip Sebo netted in injury time to give Valenciennes a last-gasp victory over strugglers Nice. Rudy Mater opened the scoring for the hosts in the 50th minute only for Nice to equalise with their first chance of the night thanks to Loic Remy.
It looked as if that would be enough for the visitors to earn a precious point, but it was not to be as Sebo came up trumps.
PSG snap streak
Paris St. Germain eased the pressure on coach Antoine Kombouare as the capital club snapped a four-game losing streak by earning a hard-fought point from a goalless draw at Nancy. Damian Macaluso went closest to settling the result in Nancy's favour, but he contrived to miss an open goal in the second half.
Struggling Le Mans failed to take advantage of Sochaux having to play with ten men for the entire second half as their match ended goalless. The visitors were reduced to ten men in the final minute of the first half when Loic Pujol was sent off for a dangerous tackle from behind on Mathieu Dossevi and they held out against Arnaud Cormier's side.
