A Wissam Ben Yedder hat-trick put Monaco on the brink of securing a direct Champions League spot for next season as they stormed back to beat Stade Brestois 4-2 at home for their ninth consecutive victory in Ligue 1 on Saturday.
Monaco were trailing 2-0 at their Louis II stadium after 23 minutes but Ben Yedder reduced the arrears before the break and netted twice in four minutes early in the second half with Kevin Volland also on target to lift them up to second place on 68 points with one game left.
Olympique de Marseille slipped down to third, on goal difference, when they slumped to a 2-0 defeat at Stade Rennes.
Benjamin Bourigeaud and Lovro Majer found the back of the net to send Rennes up to fourth place on 65 points a week before what looks like being a nailbiting finale.
The top two teams qualify directly for the Champions League group stage while the side who finish third take part in the third qualifying round.
Paris St Germain, who were already crowned champions last month, beat Montpellier 4-0 away courtesy of a Lionel Messi double with Angel Di Maria and Kylian Mbappe scoring the others.
Nice's hopes of playing in the Champions League were ended when they lost 3-1 at home to Lille, who prevailed with a Jonathan David double.
Nice are sixth on 63 points.
In the final round of matches, Monaco travel to RC Lens, Rennes to Lille and Marseille host Racing Strasbourg.
Bottom side Girondins de Bordeaux were left on the brink of relegation after a 0-0 draw against Lorient left them on 28 points, three points from a relegation/promotion playoff spot but with a much worse goal difference than 18th-placed Metz.
In Ligue 2, AC Ajaccio beat Toulouse, who were already promoted, 1-0 to secure their place in the top flight.
AJ Auxerre finished third after a 2-1 home win against Amiens and will take part in the promotion/relegation playoffs.
In Monaco, Jean-Kevin Duverne and Youcef Belaili stunned the hosts with two early goals but the principality side reacted just before the break when Ben Yedder converted a penalty after Belaili handled the ball in the area.
France forward Ben Yedder then equalised from inside the box six minutes into the second half before heading home to put Monaco ahead.
He has now scored 24 league goals and sits in second place in the scorers' standings, one behind Mbappe.
Ben Yedder also had a hand in Monaco's fourth goal as his volley was parried into the path of Volland, who finished in clinical fashion to wrap up a spectacular win.
In Rennes, Bourigeaud put the hosts ahead on 12 minutes with a low cross-shot from Martin Terrier's cutback as Marseille struggled to sustain the pace.
Terrier then broke down the left flank and his cross was met by Lovro Majer who fired home in the 35th minute.
