After defeating fourth-place Reims 3-0 on Saturday, Paris St. Germain went top of Ligue 1 thanks to a hat-trick from Kylian Mbappe.
With 27 points, champion PSG is one point ahead of Nice, who drew goalless at Montpellier on Friday.
After three minutes, Mbappe scored by neatly placing a low volley into the bottom corner of the net after receiving an unmarked cross at the back post.
In the 59th minute, he increased the lead for the visitors by dribbling past his defender and placing a low cross at the far post.
The 24-year-old French forward scored his third goal eight minutes from time with a first-time effort from inside the area.
