Paris Saint-Germain returned to winning ways in Ligue 1 after getting past Saint-Etienne 3-1, with Kylian Mbappe netting a brace.
The big-spenders were out for redemption following last week’s loss to Nantes and had three changes in goalkeeper Gianluigi Donnarumma, Nuno Mendes and Danilo Pereira.
It was the visitors that had the lead in the 16th minute when Denis Bouanga robbed Pereira off possession to go clear and beat Donnarumma.
The Gabonese international was at the fore front of another move a little to the half-hour mark as he teed-up Ryad Boudebouz from the tightest of angles, but Donnaruma saved.
PSG gradually began to find their way back and were level four minutes before halftime when Kylian Mbappe stepped into a pass from Lionel Messi to turn and fire beyond Bernardoni.

Mauricio Pochettino decided to shuffle up the stall in his offensive compartment prior to the second half and had Angel Di Maria introduced for Thilo Kehrer.
It is an invention that yielded immediate results two minutes from the restart after Mbappe ran into a clever pass from Messi to apply a smart finish past Bernardoni, which saw him become the club's second highest scorer with 156 goals.
PSG continued to pull further clear of their counterparts five minutes afterwards as Pereira made up his earlier error to head home a smart delivery from Mbappe.
There were more chances for the home side in the latter stages, after a clever shot by Di Maria forced Bernardoni into a superb save.
The Argentine had Bernardoni on the edge again when he got in the area and attempted a lob in the latter minutes, but the Frenchman was able to make the save as PSG held on for the three goals.
