Paris Saint-Germain's wait to clinch the Ligue 1 title will go on another week after they were thrashed 5-1 by Lille. The table toppers crumbled at Stade Pierre-Mauroy as second-placed Lille postponed their visitors' title celebrations by inflicting an emphatic 5-1 victory after Juan Bernat was sent off. PSG could have won the title last week but failed to do so after drawing 2-2 at home to Strasbourg.That draw featured one of the worst misses of all-time from Maxim Coupo-Moting. They went into their game against second-placed Lille on Sunday knowing that a point would be enough. But the visitors fell behind after just seven minutes. A single point at the Stade Pierre Mauroy would have sufficed for the champions to wrap up a second title in two years, but their night fell apart in spectacular fashion followign a first half in which they lost three of their starting XI. PSG remain 17 points clear at the top of Ligue 1 and will be expected to wrap up the title against Nantes in midweek, but Lille enjoyed one night of swaggering dominance as they strengthened their grip on second place.
