PARIS - Lionel Messi scored as Paris St Germain stretched their Ligue 1 lead to five points with a 3-1 win at Montpellier after Kylian Mbappe limped off the pitch on Wednesday.

Mbappe, who also missed a penalty, held his left thigh as he was replaced after 20 minutes, but coach Christophe Galtier said the France forward had damaged his knee.

"It's a knock on the knee and it hurts behind the thigh," Galtier said, not looking too worried two weeks before his team take on Bayern Munich in the Champions League last-16 first leg.

Following a lacklustre first half PSG burst into life after the break with Fabian Ruiz, Messi and Warren Zaire-Emery finding the net to put them on 51 points from 21 games.

Olympique de Marseille claimed a 2-0 victory at Nantes to leapfrog RC Lens, who dropped their first points at home in a 1-0 defeat by Nice, into second place.

Mbappe had a night to forget at La Mosson, having had his spot-kick parried away by Benjamin Lecomte in the eighth minute. He had to take it again, only for the Montpellier keeper to deny him again.
