PSG manager Thomas Tuchel said his side's 3-0 victory over ten-man Amiens was "deserved" as they extended their lead at the top of Ligue 1 to 13 points.
Edinson Cavani gave PSG the lead from a spot-kick after a goalless first half with Amiens managing just one shot on target in the 90 minutes.
Khaled Adenon was sent off for a second bookable offence after he brought down the marauding Kylian Mbappe before the French forward added his side's second minutes later.
Brazilian defender Marquinhos added a third to wrap up the game after being expertly set up by Julian Draxler, who took the ball past defenders to slide into the path of Marquinhos.
Tuchel spoke of the importance of the win after his PSG side were knocked out of the League Cup on Wednesday by Ligue 1 strugglers Guingamp.
Speaking after the game Tuchel told the club website: "It's a deserved win after a good performance from us.
"We can't control the result, but we can control our level of performance and that's what we did today.
"We were focused, we showed quality and I'm happy with what we did today."
Draxler added: "We created several chances in the first half, but we needed to wait until the second to make the breakthrough.
"It wasn't easy, they closed down the space, but it was easier after the red card."
Amiens boss Christophe Pelissier told the club website it was "very very hard" after his side had played well before the penalty changed the game.
He said: "It's too bad because for 50 minutes which were really good, we did what we wanted to do."
