Paris Saint-Germain extended their lead atop Ligue 1 to 13 points as they thumped nine-man Montpellier 5-0.
Montpellier were already behind when goalkeeper Dimitry Bertaud was sent off in the 17th minute on Saturday to end their hopes of being competitive.
Pablo Sarabia had scored a fine eighth-minute opener, with PSG going on to net twice in the final five minutes of the first half through Angel Di Maria scoring and a comical Daniel Congre own goal.
Thomas Tuchel's men kept a fifth consecutive clean sheet as they went a 19th straight match without losing, with second-half strikes from Kylian Mbappe and Layvin Kurzawa adding gloss to the victory prior to a late sending off for Montpellier's Joris Chotard.
