PSG's Ligue 1 title hopes have taken a hit after being forced to come from behind to secure a 2-2 draw against Brest on Sunday.
Antoine Kombouare's PSG outfit had to wait until the 86th minute to steal a point at Brest, thanks to a goal from striker Guillaume Hoarau.
The capital side had gone ahead through a 21st-minute strike from midfielder Mathieu Bodmer, but they headed into the interval a goal down after Brest's Larsen Toure and Bruno Grougi found the net, the latter in first-half stoppage time, giving their side the lead.
But Hoarau's goal put PSG within six points of Lille, while Brest move to 11th on the back of their three-game unbeaten run.
A goal from substitute George Welcome helped Monaco out of the relegation zone with a shock 1-0 win over fifth-placed Stade Rennes.
The on-loan Honduran attacker scored the 73rd-minute winner as Stade Rennes slumped to a third-straight loss.
Bordeaux, meanwhile, shot into sixth spot on the back of a 2-0 win over Saint-Etienne.
Goals from Czech midfielder Jaroslav Plasil and substitute Cheick Diabate helped them above their defeated opponents.
Nancy missed a great chance to gain some breathing space in their relegation battle after only managing a 0-0 draw against a 10-man Arles.
Competing against the relegation-bound side, Nancy failed to beat Arles goalkeeper Cyrille Merville, even after defender Dianbobo Balde was sent off in the 10th minute.
Nancy are two points clear of the relegation zone, while Arles will be playing Ligue 2 football next season.
In other games, Valenciennes and Sochaux played out a 1-1 draw in their mid-table clash.
Auxerre and Lens also finished 1-1 in a result that does neither side any favours in their relegation battles.
Toulouse are winless in four outings after their 1-1 draw with Caen, which keeps them both locked in a battle to avoid the drop.
