Meanwhile, the stewards struggled to hold back the fans who invaded the pitch.
A furious Jorge Sampaoli had to be restrained as well by his staff and players as the incident unfolded.
The match had to be suspended around the 76th minute but Nice did come back onto the pitch to complete the game once the situation calmed down.

As per the latest reports, Marseille are set to contend the decision later and they will demand that the outcome of the match is reversed.
We need to set precedents for French football. The referee was with us, he confirmed that to us, that safety was not assured. His decision was to abandon the match, but the LFP decided to restart the match. It is not acceptable for us.𝗣𝗮𝗯𝗹𝗼 𝗟𝗼𝗻𝗴𝗼𝗿𝗶𝗮, Marseille President
