Angel Di Maria scored a sumptuous free-kick and Kylian Mbappe was also on target as PSG continued their relentless march towards another French title by hammering Montpellier 5-1 on Wednesday.
With Neymar and Edinson Cavani still absent, Layvin Kurzawa also scored at the Parc des Princes, while two own goals completed the rout.
Florent Mollet had equalised at one point in the first half for the visitors before they crumbled in a rearranged fixture that had been postponed in early December due to disruption caused by "yellow vest" protests.
As they warm up for the second leg of their Champions League last-16 tie against Manchester United on March 6, PSG are now 15 points clear of second-placed Lille, and still have a game in hand.
"It came down to patience, and quality, and a bit of luck as well," said PSG coach Thomas Tuchel after his side maintained their perfect home record in the league this season.
