Neymar and Kylian Mbappe were missing but Paris Saint-Germain ominously moved six points clear at the top of the Ligue 1 table.
Julian Draxler, Edinson Cavani, Angel Di Maria and Moussa Diaby were all on target as Paris Saint-Germain continued their strong start to the season with a routine 4-0 Ligue 1 win at home to Saint-Etienne.
Neymar was rested ahead of Tuesday's Champions League trip to Liverpool while Kylian Mbappe was serving the first game of a three-match ban after his red card against Nimes last time out.
Saint-Etienne wasted a host of early chances in Friday's meeting at the Parc des Princes and Julian Draxler's terrific header earned the Ligue 1 champions a 22nd-minute advantage.
