Monaco solidified second position in Ligue 1 with a 4-0 rout of Dijon on Friday night at the Stade Louis II stadium.
Goals from Keita Balde, Fabinho, Rony Lopes and Kamil Glik earned a comfortable victory which moves them four points ahead of Marseille, who play on Sunday.
Monaco had already threatened by the time Balde opened the scoring in the 13th minute as the Senegal international converted Djibril Sidibe's centre to mark his return from suspension with a goal.
Fabinho doubled the lead in the 69th minute as he converted from the spot after Thomas Lemar was fouled.
Lopes made it three in the 87th minute when he fired home a rebound and then Glik sealed Monaco's biggest home win since August in time added on.
The success moves them to within nine points of leader Paris Saint-Germain, but a second successive Ligue 1 title still looks out of reach for Leonardo Jardim's men.
