St Etienne 0-1 Paris St-Germain
Paris St-Germain moved level on points with second-placed Marseille in Ligue 1 after Zlatan Ibrahimovic's penalty secured victory at St Etienne.
Ibrahimovic, who claimed a laser had been pointed in his face by a fan as he prepared to shoot, slotted home after Jeremy Clement handled in the box.
Edinson Cavani came close to doubling the visitors' second-half lead but his lob hit the crossbar.
St Etienne remain fourth while PSG stay within four points of leaders Lyon.
Les Verts headed into the match at the Stade Geoffroy-Guichard seeking revenge for a 5-0 defeat in the reverse fixture against Paris St-Germain in August.
Ibrahimovic scored a hat-trick in that game at the Parc des Princes and on Sunday the Swede ended Les Verts' 12-match unbeaten run with his sixth goal in three league games against them.
Elsewhere, Lyon striker Alexandre Lacazette scored from the spot to bring his goal haul to 21 for the season and help secure a 2-0 victory at Metz, but Ligue 1's top-scorer failed to finish the game after going off injured.
Caen rose up from the bottom of the table after goals from Sloan Privat, Lenny Nangis, Julien Feret and Damien Da Silva secured a shock 4-1 victory away to Rennes.
Evian leapfrogged Toulouse and edged away from the relegation zone after Adrien Thomasson's early goal gave the home side a 1-0 win.
Nineteenth-placed Lens played out a 0-0 draw at mid-table Reims.
