PSG dominated the early exchanges as they looked to bounce back from their defeat to Liverpool on match day one.
Neymar's opener came 20 minutes in when he was fouled, and he put the ensuing free kick inside the post and inside the goal for the 1-0 lead.
Angel Di Maria, Edinson Cavani and France World Cup victor Kylian Mbappe added a goal each as the French champions ripped into 1991 European Cup winners Red Star, who were spared a heavier defeat by goalkeeper Milan Borjan.

The French league leaders scored again two minutes later as Neymar found Mbappe before meeting the return pass with a lovely cushioned finish.
The third goal arrived in the 37th minute through Edinson Cavani, who showed good footwork to get into the box before slotting home with a deflected effort.

Red Star did a goal back four minutes thanks a strike from substitute Marko Marin, who drilled a fine effort past Alphonse Areola.
Red Star supporters were given something to celebrate as Marin, the former German worldwide winger whose career lost its way after a move to Chelsea, blasted into the roof of the net for a consolation goal in the 74th minute.
