Nicolas Pepe became the first Lille player since Eden Hazard to score 19 goals in a single Ligue 1 season after his match-winner against Paris Saint-Germain on Sunday.
In the 51st minute, the Cote d'Ivoire forward made it 2-1 against the 10-man Parisians. The game had started in their favour after Thomas Meunier's seventh-minute own goal but Juan Bernat leveled four minutes later.
The left-back was then shown a straight red card just before the interval.
Jonathan Bamba, Gabriel and Jose Fonte scored more goals to condemn PSG to a 5-1 defeat, thus, extending their wait for the Ligue 1 trophy.
