Zlatan Ibrahimovic has struck twice in the first half to give Paris Saint-Germain a 2-1 lead over Lille.
Les Dogues were caught napping as the Swede gave Carlo Ancelotti's men the perfect start inside the first minute.
The hosts drew level through Aurelien Chedjou, who got his head on Dimitri Payet's corner in the 12th minute.
Les Parisiens retook the lead when Javier Pastore threaded the ball through for Ibrahimovic to shoot across Mickael Landreau and into the net.
