PARIS -- Monaco consolidated second place and put leader Paris Saint-Germain's title celebrations on hold by winning 1-0 at Rennes in the French league on Saturday.
PSG could have clinched the title this weekend if Monaco lost and it won on Sunday at Lyon. For now, Monaco pulled within 10 points of the leader.
Emmanuel Riviere chased a through ball from Jeremy Toulalan to score with a sliding effort in the 55th minute. Riviere then had a close-range attempt diverted onto the bar by Rennes goalkeeper Benoit Costil in the 63rd.
Lille kept pace with Monaco, staying six points behind in third, by edging Valenciennes 1-0.
Divock Origi took a pass from Salomon Kalou to score with a low strike in the 70th minute.
"It wasn't easy but the most important thing is to take the three points," Lille coach Rene Girard said. "It seemed to me that we missed a bit of gas in the tank, a bit of freshness. But the boys managed to do what they needed to do."
Elsewhere, Ajaccio midfielder Mehdi Mostefa volleyed home in the 86th to salvage a draw and delay his team's relegation after Bordeaux substitute Jussie opened the scoring in the 62nd.
Sochaux kept its slim hopes of safety alive by defeating Toulouse 2-0 to climb to 18th place. Jordan Ayew headed in a cross from winger Roy Contout to put the hosts ahead in the 15th before returning the favour in the 49th for Contout, who doubled the lead with a header.
Evian beat Bastia 2-1 to move eight points clear of the relegation zone. Denmark international Daniel Wass scored the winner with a powerful free kick in the 48th.
Vincent Aboubakar scored in stoppage time his 14th league goal in a 2-1 win over Nice to fire Lorient into the middle of the table. Gilles Sunu gave Lorient the lead in the 19th before Nice leftback Timothee Kolodziejczak levelled by converting a rebound in the 30th.
On Sunday, Saint-Etienne faces Reims and Nantes hosts Guingamp.
On Friday, Marseille edged Montpellier 3-2 to keep alive its slim hopes of a European spot.
