Paris Saint-Germain have moved to the top of Ligue 1 on goal difference after seeing off new boys Gazelec Ajaccio at the Parc des Princes.
Laurent Blanc's side went ahead inside 11 minutes when Blaise Matuidi produced a thunderous shot to beat Clement Maury at his near post.
Gregory Pujol had a chance to pull the visitors back on level terms when he latched on to Damian Djokovic's cross, but he failed to trouble Kevin Trapp with his effort.
Instead, the Corsicans fell further behind as Thiago Silva was allowed a free header from close range, nodding home Thiago Motta's corner.
Maxwell almost created a third goal just after the half-hour mark when his cross from the left side reached Jean-Kevin Augustin, who headed narrowly wide.
David Luiz then tried his luck on the stroke of half time with a free kick from 30 yards out, but the ex-Chelsea man's effort was easily collected by Maury.
Soon after the restart, PSG continued to apply pressure to the Gazelec defence and nearly scored again, with Edinson Cavani failing to beat the Ajaccio keeper with a glancing header from Lucas Moura's cross before Augustin missed another opportunity from a tight angle soon after.
Les Parisiens threatened once more late on when Serge Aurier saw his header saved by Maury as the Ivorian went in search of a first goal in PSG colours.
However, despite further efforts from Cavani late on, Blanc's side were forced to settle for a 2-0 win, but still move to the top of the table on goal difference.
