Monaco restores their three-point lead at the top of Ligue 1 with an easy victory with relegation-threatened Nancy on Saturday.
The scoreline began Tobias Badila’s own goal which put the visitors ahead.
Bernardo Silva doubled their lead before the break with a goal of his own.
Thomas Lemar finished with the final goal of the match, four minutes from time as Monaco made it 98 league goals in 35 games so far this season.
Paris Saint-Germain had earlier beaten Bastia 5-0 to draw level on league points with Monaco, but they still have a game in hand.
Monaco has a far superior goal difference to PSG. Realistically they just need one win from their final three matches to become champions for the first time since 2000.
