A lacklustre Paris St Germain dropped down to third in Ligue 1 after Tino Kadewere earned visitors Olympique Lyonnais a 1-0 victory at the Parc des Princes on Sunday.
The French champions, whose forward Neymar sustained a possible ankle injury in stoppage time, were never in the mix as they surrendered top spot to Lille, who claimed a no-nonsense 2-1 win at home against Girondins de Bordeaux earlier.
Lille have 29 points from 14 games, leading second-placed Lyon on goal difference with PSG on 28 points after their fourth defeat of the season.
Olympique de Marseille are fourth on 27 points with two games in hand, in a tight top five separated by three points.
