PSG Title Party Delayed Again After Historic Thumping At Lille
The loss was PSG's worst domestic defeat since 2009, and the first time they had conceded five goals in the league since 2000.
PSG's Ligue 1 title party put on hold by Lille
PSG thrashed 1-5 by Lille on Sunday
This was PSG's biggest league defeat in 10 years
Paris Saint-Germain missed the chance to seal their sixth Ligue 1 title in seven years for the second week running on Sunday after a 5-1 hammering at Lille, their biggest league defeat in 10 years. Thomas Tuchel's side could have been crowned champions in record-equalling time last weekend but failed to beat Strasbourg, and they fell short again on Sunday despite needing just a point in a match that saw them have to play with 10 men for 54 minutes and lose both captain Thiago Silva and Thomas Meunier to injury.
The loss was PSG's worst domestic defeat since going down 4-0 at Bordeaux in 2009, and the first time they had conceded five goals in the league since another 5-1 defeat at Sedan way back in 2000.
However they are still 17 points clear of second-placed Lille and if they win at Nantes on Wednesday they will still win the league with six matches to spare.
"We are going to be champions, but you have to lose in the right way," said Kylian Mbappe, who had two goals ruled out for offside.
"We can't lack personality like that, and concede three, four, five goals. Losing happens, but that is not normal."
World Cup winner Mbappe had already had one goal chalked off by the officials when a comical Meunier own goal set Lille on their way after six minutes.
But PSG looked set to seal the title when Juan Bernat levelled soon after and Mbappe roofed what looked like his 28th league goal of the season in the 13th minute, only to see that one also rightly disallowed.
Silva left the field with a knee injury soon after and after Meunier was pulled off, Bernat was then handed a debatable straight red card in the 36th minute for a tug on Nicolas Pepe despite a VAR check.
Attacker Pepe slotted home Lille's second five minutes after the break when he latched onto a superb Jonathan Ikone through ball and after that the floodgates opened.
Jonathan Bamba smashed home the third 14 minutes later from another Ikone assist and two fine headers from Gabriel and Jose Fonte in the final 20 minutes completed the rout and put Lille eight points ahead of third-placed Lyon.
"Putting five past PSG doesn't happen to everyone, even if they did only have 10 men, but we played well tonight," Pepe told Canal+.
"We've still got six matches left and we need to win at least three or four to be assured of the Champions League next season."
Saint-Etienne on Euro hunt
Earlier on Sunday, Saint-Etienne closed in on Champions League football after Mathieu Debuchy scored twice in a 3-0 win over Bordeaux that moves them to within three points of Lyon.
Wahbi Khazri opened the scoring from the spot 10 minutes after the break following a VAR check of Sergi Palencia's handball before Debuchy headed home the second from a corner to seal the points 17 minutes before the end.
Debuchy then completed the win with a deflected close-range strike in the final minute to put Jean-Louis Gasset's side back ahead of Marseille, who started the day fourth and in the Europa League spot after surviving late VAR penalty drama on Saturday to scrape to a 2-1 win over Nimes.
They are two points ahead of Rudi Garcia's side and piling pressure on Lyon, who have lost two on the bounce following Friday's shock 2-1 defeat at Nantes.
Lyon go into the final six games in trouble following coach Bruno Genesio's announcement that he would leave the club in the summer after falling out of favour with the fans.
Monaco moved to two places and seven points clear of the relegation play-off spot despite only drawing 0-0 with Reims after all four of the teams below them failed to win.
Caen lost 1-0 to Angers, Giungamp draw 3-3 at Strasbourg, while Dijon and Amiens drew 0-0 in a match that was interrupted after monkey chants were directed by a home fan towards the away side's captain Prince Gouano.
