PARIS, Jan 13 (Reuters) - Olympique Lyon slumped to their second league defeat of the season when they lost 2-0 at Toulouse in their first Ligue 1 match of the year on Saturday.
Lyon, resuming their quest to become the first side from a major European league to win six titles in succession, fell behind on the hour when Cameroon forward Achille Emana scored.
Sweden forward Johan Elmander sealed Toulouse's win after 82 minutes, storming past three defenders to beat goalkeeper Remy Vercoutre who was deputising for the injured Gregory Coupet.
Lyon still comfortably lead the standings, with 50 points from 20 games, 14 points ahead of second-placed Racing Lens.
Northerners Lens needed a late goal by Brazilian substitute Jussie to snatch a 1-1 home draw with Lille in a tight derby.
The forward volleyed home from inside the box six minutes from time to give Lens a share of the points from a tactical affair with few highlights.
Lille, who had opened the scoring after 70 minutes courtesy of Brazilian defender Michel Bastos, climbed one spot to fourth, 18 points off the pace.
Paris St Germain had earlier stumbled to an embarrassing 2-1 home defeat by fellow strugglers Valenciennes.
The troubled club from the capital slid to 17th, one spot above the drop zone, with just 19 points from as many games.
Valenciennes, who remained 14th after their first away win since they returned to the top flight this season, were reduced to 10 men when Dutch midfielder Patrick Paauwe was sent off for a second booking in the 51st minute.
That did not stop the northerners scoring twice, with a header by striker Steve Savidan just after the hour and a deflected volley from substitute midfielder Sebastien Roudet with two minutes remaining.
Former Portugal striker Pauleta, the PSG captain, reduced the arrears with a penalty in added time.
