PSG extended their lead at the top of Ligue 1 to five points after defeating Auxerre in their final match before the World Cup.
Lionel Messi played a lovely chipped ball over the top to Nuno Mendes, who found Kylian Mbappe in the middle and the PSG striker volleyed home in the 11th minute at the Parc des Princes.
That was one of only two shots in the first half for PSG, which was their lowest total in a league game since May 2021.
Carlos Soler doubled the lead in the second half with a deft header from a Mendes cross, before putting Achraf Hakimi through to coolly stroke in the third.
As Auxerre began to tire, the hosts scored two more goals in the final nine minutes.
Renato Sanches, who had been left out of Portugal’s World Cup squad earlier in the week, scored the fourth, and with six minutes remaining, Hugo Ekitike caught Julian Jeanvier dallying on the ball, nipped in, and slotted past visiting keeper Benoit Costil.
PSG, who had won 13 and drawn two of their first 15 league games, re-established a five-point lead over second-placed Lens, with Rennes a further five points behind.
