PSG beat Boulogne with second-half blitz
The capital club moved up to seventh in the standings on 22 points, six behind leaders Girondins Bordeaux. Boulogne remain in the bottom three on nine points.
The hosts opened the scoring against the run of play nine minutes before the break when midfielder Guillaume Ducatel benefited from a bad clearance by Sylvain Armand to unleash a 30-metre thunderbolt that went under Apoula Edel's bar.
Ludovic Giuly's substitution by striker Peguy Luyindula in the 58th minute, inspired PSG's comeback.
The French striker's pass found Clement Chantome in the area and the midfielder fired into the roof of the net to level just after the hour.
Luyindula put PSG ahead on 64 minutes when he converted a penalty after Mevlut Erding was brought down, Turkey striker Erding then headed home a third three minutes later and the same player made it 4-1 from close range soon after after being set up by Luyindula.
Johann Ramare reduced the arrears with a penalty eight minutes from time, only for Jean-Eudes Maurice to score a fifth for PSG.
