Unheralded Lorient moved into a share of top spot in the French first division on Saturday with a 2-1 defeat of champions Lyon while Paris Saint Germain faced up to an early-season crisis.
Lorient now have 10 points from their four games and are top along with Le Mans, who drew 1-1 with Lille, who have an identical points and goal record.
Marama Vahirua scored both Lorient goals, the first a spectacular volley after 14 minutes to put Lyon on the backfoot but Karim Benzema levelled for the champions on the half-hour mark.
Tahiti-born Vahirua popped up again to score the winner in the 64th minute to send his side top.
Nicolas Fauvergue gave Lille a 33rd minute lead at Le Mans with a fine header and was then unlucky not to add a second in stoppage-time at the end of the first half when a fierce drive came back off the post.
Le Mans made the most of the let-off when Brazilian striker Grafite levelled in the 56th minute to give his side a point.
Paris Saint Germain coach Paul Le Guen saw his problems pile up with a dull 0-0 draw at rock-bottom Metz.
Giant Czech striker Jan Koller scored twice as Monaco beat Sochaux 3-0 to register their second win in three days and move into fourth place.
Jeremy Menez, a former Sochaux player, hit the second.
Eric Mouloungui, James Fanchone and Kevin Gameiro scored the goals which gave Strasbourg the three points at Toulouse for whom Andre-Pierre Gignac grabbed a consolation goal.
The win put Strasbourg into fifth place while Toulouse are six places off the bottom.
