Paris St-Germain have made it five wins out of five in Ligue 1 this season after an emphatic win over promoted side Clermont.
Without Lionel Messi and Neymar following their late return from international duty, PSG were still way too good for their opponents.
Herrera scored a brace in the first half to put the home side in control. Kylian Mbappe slotted in a coolly taken third before Idrissa Gueye rounded off the rout with a header.
Next on their schedule is a trip to Belgium to face Club Bruges in their Champions League opener on Wednesday. The Paris club now leads the table with 15 points.
In their first in the French top flight, Clermont had been impressivel but their first defeat leaves them third on eight points.
