Lille moved back top of Ligue 1 on Sunday after holding Paris Saint-Germain to an uninspiring goalless draw which failed to live up to its pre-match billing.
Lille take first place in the French top flight from Lyon on goal difference after a match which saw just a handful of shots on target and very little in the way of incident.PSG are a point back in third after failing to create anything from their territorial dominance, shorn of attacking inspiration without Neymar and Mauro Icardi, among others, while Kylian Mbappe started on the bench as he reportedly struggles with a thigh knock.
Marseille meanwhile are five points behind the leaders after their 1-1 draw with Reims on Saturday, although Andre Villas-Boas' side do have two games in hand on their title rivals.
"I saw a very strong performance from my team," insisted PSG coach Thomas Tuchel.
"We lacked a lot of quality but we played well. We were very disciplined and we never lost our structure."
PSG were the stronger side in a dismal first half which didn't see a shot on target until Moise Kean's weak flicked header was easy collected by Mike Maignan in the 42nd minute.
Lille, who on Friday were sold to Callisto, a subsidiary of the Merlyn Partners investment fund, struggled to get a foothold in the biggest match of their league campaign so far.PSG's dominance continued in the second period but they were lacking their usual creative spark, and the highlight of the latter stages was Presnel Kimpembe's superb tackle on Burak Yilmaz with Lille charging towards goal on the break.
