Brazilian midfielder Nene scored both goals as Monaco beat Lens 2-0 on Sunday to close within two points of French league leader Lyon.
Meanwhile, Kevin Gameiro set up three goals and netted one to lift Lorient over Nice 4-1, and Toulouse edged Paris Saint-Germain 1-0.
Monaco is in fourth place with 18 points, Lorient remained sixth with 17 points, and PSG missed an opportunity to make up ground, dropping to ninth place with 13 points.
“At this moment, we feel good in fourth place,” Monaco goalkeeper Stephane Ruffier said. “But we shouldn’t get too excited. Let’s keep on taking it one match at a time.”
In Monaco, Nene slammed home a rebound in the ninth minute after a header from South Korea forward Park Chu-young crashed against the post. He followed up by scoring from the penalty spot in the 67th after Romain Sartre fouled Park.
The goals took the Brazilian midfielder’s tally to seven goals this season, making him the top scorer in the league.
Lens slipped into the relegation zone with just eight points.
In Lorient, the home side opened the scoring in the 39th. Kevin Gameiro pulled the ball back for Marama Vahirua, who fooled the Nice defense with a dummy and let the ball continue through to Arnold Mvuemba, who found the net with a powerful shot.
Vahirua then pounced on a loose ball to make it 2-0 in the 48th after Nice goalkeeper David Ramirez Ospina had failed to catch a cross from Gameiro.
Loic Remy curled home a free kick for Nice in the 62nd, notching his fourth goal of the season.
But Gameiro beat Ospina to the ball in the 77th to feed Sigamary Diarra, who flicked into an empty net. Gameiro then put the result beyond doubt in the 88th with an angled shot.
Nice remained in the relegation zone, level on points with Lens.
In Toulouse, Albin Ebondo collected a pass from France international Moussa Sissoko to slip the ball past PSG goalkeeper Gregory Coupet in the 74th for the winner.
PSG had the only scoring chance in the first half with a bouncing shot from Peguy Luyindula that was turned around the post by Toulouse goalkeeper Yohann Pele in the 11th.
Pele jumped to palm away a long-range strike from Younousse Sankhare in the 85th and preserve the win.
Both teams struggled to string together moves on a poor pitch that was covered with sand and which is also used for rugby matches.
Toulouse climbed to 12th place with 11 points.
Lyon lost to Sochaux 2-0 Saturday, its first defeat of the season, but stayed top of the league.
Promoted Montpellier beat 10-man Saint-Etienne 2-1 to join Lyon on 20 points, while defending champion Bordeaux lost 1-0 to Auxerre to drop to third on 19 points.
Also Saturday, it was: Nancy 0, Marseille 3; Valenciennes 2, Grenoble 0; Le Mans 1, Boulogne 1; and Lille 0, Rennes 0.
