Paris Saint-Germain drew 2-2 with Lille on Sunday in Ligue 1 to extend their lead to three points at the halfway stage.
Sweden striker Zlatan Ibrahimovic gave PSG the lead in the 36th minute with a 25-yard free kick that took a deflection off the Lille wall.
But Lille captain Rio Mavuba pounced on a low cross from Salomon Kalou to level with a first-time effort in the 44th before Kalou converted a penalty in the 53rd minute.
The hosts equalised with an own goal from Lille centerback Marko Basa in the 72nd minute.
Tensions sometimes flared in a match pitting the most prolific offense in the league, PSG, against the tightest defense, Lille. Mavuba and Ibrahimovic were booked for shoving each other in the 40th minute.
Lille stayed in third place, one point behind Monaco.
Also Sunday, Marseille rallied from a two-goal deficit to draw 2-2 with Bordeaux.
At Stade Velodrome, Bordeaux converted their first scoring chance when Brazilian striker Jussie outjumped Marseille midfielder Alaixys Romao to head in a corner in the 34th minute.
Bordeaux forward Nicolas Maurice-Belay capitalised on a mistake from Kassim Abdallah to double the lead with a low diagonal strike in the 66th minute.
However, a lapse of concentration by Bordeaux players allowed the hosts to equalise quickly. Bordeaux goalkeeper Cedric Carrasso palmed a free kick from Florian Thauvin into the path of Romao, who flicked home in the 73rd minute.
Marseille striker Andre-Pierre Gignac then beat Maxime Poundje to the ball to convert a cross from Benjamin Mendy a minute later.
Bordeaux stayed in fourth place in the table and Marseille is sixth.
Lyon conceded a 2-2 draw at Lorient in the last minute of stoppage time but ended Lorient's five-game winning streak.
Yoann Gourcuff set up Lyon midfielder Clement Grenier, who opened the scoring with a first-time effort in the bottom corner in the 21st minute. Lyon striker Bafetimbi Gomis made it 2-0 by converting a rebound after goalkeeper Baptiste Reynet parried an attempt from Alexandre Lacazette in the 49th minute.
But Lorient forward Vincent Aboubakar cut Lyon's lead to 2-1 by notching his 11th league goal this season with a low strike in the 60th before substitute Alain Traore headed in a cross from Raphael Guerreiro in the third minute of stoppage time.
