Paris St Germain clung on to their hopes of winning a fourth consecutive Ligue 1 title with a 4-0 home win against 10-man Stade de Reims as Lille's lead was cut to a single point with one game remaining on Sunday.
As PSG cruised to a routine victory, Lille, who have 80 points, were held to a goalless draw by mid-table St Etienne and now need a win at Angers in the final round to guarantee them a first title since 2011.
Neymar converted a penalty in the 13th minute after Yunis Abdelhamid handled the ball in the area and picked up a straight red card in the process. Kylian Mbappe doubled the advantage in the 24th, firing home from a terrible clearance by Thomas Foket.
Marquinhos added a third with a downward header on 68 minutes and Moise Kean netted a fourth from just inside the box.
"We saw that today, Liverpool's keeper (Alisson Becker) scored a last-minute goal, so anything is still possible," said PSG midfielder Ander Herrera. "We're now going to focus on next Sunday to win that final," said Lille captain Jose Fonte.
