Kevin Gameiro has capped his return to the Stade de Mustoir with a brace as Paris Saint-Germain triumphed 3-2 over Lorient.
The visitors dominated possession in the first half, but they could not find a way through. An injury to Ezequiel Lavezzi in the 18th minute saw former Lorient striker Kevin Gameiro enter the fray.
The 26-year-old supplied a cross for Zlatan Ibrahimovic to break the deadlock in the 31st minute, but the Swede got his header wrong and missed the target.
It remained goalless at half time, but Les Parisiens finally made the breakthrough six minutes after the restart. Ibrahimovic was found once again by Gameiro, but this time made no mistake in finding the net.
The roles were reversed when Gameiro notched the first of his two goals in the 62nd minute, as this time Ibrahimovic turned provider. Three minutes later, Gameiro capped a fast counter-attack to put Carlo Ancelotti's men out of sight.
Second-half substitute Ronan Le Crom saw red for fouling Julien Quercia inside the area, which also gave the hosts a chance for consolation, which Arnaud Le Lan tucked away.
It did not stop the French champions from earning all three points, which sees them finish 12 clear of second-placed Marseille.
