AS Monaco lost for the fourth time in five games as a rampant Olympique Lyonnais hammered them 3-0 on Sunday to move into third place in Ligue 1.
The loss left Monaco, runners-up last season and champions in 2017, second bottom of the standings with 13 points from 17 games, five clear of last-placed Guingamp.
They have conceded 45 goals in all competitions this season, the most by any team in Europe's top five leagues.
Houssem Aouar scored Lyon's first after six minutes when he finished off a rebound close to goal and Nabil Fekir made it two 11 minutes before halftime.
Aleksandr Golovin made Monaco's plight even more difficult when he got a straight red for a bad tackle early in the second half and Ferland Mendy compounded the misery for Thierry Henry's side when made it 3-0 with a header.
Lyon have 31 points after 17 games, three behind Lille, who moved into second earlier in the day with a 3-2 win at Nimes.
Lille's first league victory in Nimes since 1954 put the northern side on 34 points from 18 games, three above Lyon and five ahead of fourth-placed Montpellier, who have played two fewer games.
Paris Saint-Germain remain runaway leaders with 44 points from their unbeaten 16-game start.
Ligue 1 has been disrupted over the last two weeks as several games were postponed because of widespread anti-government protests across France.
With many matches still to be rescheduled, some teams have played two games more than others.
