Mbappe, whose continued presence at the Parc des Princes was confirmed before kick-off, struck twice within four first-half minutes before Neymar made it 3-0, and then completed his treble within five minutes of the restart.

The home side led twice through Timothy Weah, whose second came just two minutes from time, but Benjamin Bourigeaud and Guirassy ensured it finished 2-2.
That meant Andy Delort's heroics counted for little after he scored a remarkable seven-minute hat-trick to fire Nice to a 3-2 victory at Reims.

In Serie A, Martin Hongla's late equaliser banked Verona a point from a thrilling 3-3 draw at Lazio.
The visitors raced into a 2-0 lead inside 14 minutes through Giovanni Simeone and Kevin Lasagna, and although the hosts were level before the half-hour mark thanks to Jovane Cabral and Felipe Anderson and went ahead through substitute Pedro, Martin Hongla's 76th-minute goal meant it finished all square.
