Paris Saint-Germain put their swine flu woes behind them and recorded their first victory since the end of August by winning 4-1 at Sochaux in the French top flight on Sunday.
Jeremy Clement was one of the players to have contracted the virus that prompted the last-minute postponement of PSG's match at Marseille last weekend but he struck the opening goal before Clement Chantome notched the second.
Mevlut Erding claimed the third on his return to his former club and Peguy Luyindula was also on target as PSG climbed above Sochaux into 10th place while retaining a game in hand.
Their last victory was a 3-0 triumph at home to Lille on August 30.
Earlier, Valenciennes moved up to sixth with a fine 3-0 victory at Rennes, while Nice followed up their shock 4-1 win over Lyon last weekend by beating 10-man Le Mans 1-0.
Turkey international striker Erding was making his first start after missing PSG's previous six games with a shoulder injury and he spurned his first chance by blazing over from Chantome's pass in the 11th minute.
Erding was then given the opportunity to put the visitors ahead after home goalkeeper Teddy Richert was harshly adjudged to have felled Luyindula in the area, but although Richert did brilliantly to save both Erding's penalty and Christophe Jallet's follow-up, the second rebound was converted by Clement.
Stephane Sessegnon and Luyindula both came close to extending the visitors' lead early in the second period before Chantome made the points safe in the 57th minute, racing clear and lifting a delightful finish over Richert.
Erding clipped home Jallet's cross at the near post with 15 minutes to play and Luyindula rounded things off late on after Stephane Dalmat had netted a 25-yard consolation for the hosts.
Rennes, beaten just twice in their previous 27 league home games, bossed the first half at the Stade de la Route de Lorient but fell behind in the 58th minute when Bobo Balde headed in Fahid Ben Khalfallah's free-kick.
Ben Khalfallah sealed the points for Valenciennes in the 78th minute, striding forward from midfield and bending a shot past Rennes goalkeeper Nicolas Douchez, before Gregory Pujol added a third four minutes from time.
The win moves Philippe Montanier's side above Rennes, Nancy, Lorient and Marseille into sixth place in the table and they also top the goalscoring charts with 22 strikes to date this season.
