Paris St-Germain moved five points clear at the top of the table with a convincing win over Auxerre in their last match before the World Cup.
Kylian Mbappe volleyed home in the 11th minute after Lionel Messi played a lovely ball over the top to Nuno Mendes, who found him in the middle.
That was the only shot they had in the first half, which was their lowest total in a league game in over a year.
The cutting edge came in the second half as Carlos Soler doubled the lead with a deft headed from a Mendes cross, before Achraf Hakimi stroked in the third.
The hosts scored two more times in the last nine minutes.
Renato Sanches, left out of the Portugal World Cup squad earlier in the week, produced a tidy finish for the fourth and, with six minutes left, Hugo Ekitike caughtJulian Jeanvier dallying on the ball, nipped in and scored.
Paris Saint-Germain, who have won 13 and drawn two of their first 15 league games, re-established a five-point gap between themselves and second-placed Lens, with Rennes a further five points back, thanks to their victory over Caen.
