Kylian Mbappe had a night to forget as he missed two penalty attempts and an open goal rebound on the second before being forced off with injury after just 20 minutes.
The French side were awarded a spot-kick in the early stages of the Ligue 1 clash with Montpellier and Mbappe stepped up to take it.
Surprisingly the usually cool Frenchman saw his effort saved but he was given a second chance when VAR ruled that players had encroached the area.
However, this time his effort came back off the upright before he blazed the rebound well over with the keeper lying stranded.
Mbappe’s night then went from bad to worse as he suffered an apparent thigh injury and had to be substituted with less the a quarter of the game played.

This is especially worrying for Les Parisians with the first leg of their Champions League showdown with Bayern Munich just two weeks away.
PSG did manage to get the job done without him though as Lionel Messi took over and scored in a 3-1 victory, seeing them move five points clear.
PSG burst into life after the break with Fabian Ruiz, Messi and Warren Zaire-Emery finding the the net to put them on 51 points from 21 games.
Speaking after the game, coach Christophe Galtier suggested the injury was down to a knock rather than a muscle problem.
‘He took a knock to the back of the knee or the back of the thigh, so we’ll see,’ said Galtier. ‘I’m not too worried. It’s a bruise or a contusion, we don’t know yet.
‘With the run of matches we don’t want to take risks with a very busy fixture list, but it doesn’t appear that serious.’
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.
