Paris Saint-Germain coach Laurent Blanc has called on the league's governing body to take drastic steps in a bid to eradicate crowd trouble at football matches.
Sunday's Ligue 1 clash between Marseille and Lyon at Stade Vélodrome was marred by crowd trouble, leading to the match being delayed for over 20 minutes.
While Blanc criticised the supporters responsible for the disruption, he was quick to point out that this was not the first incident of this nature in recent times.
The former France international has called on the country's football authorities to take drastic action, especially as all eyes will be on France ahead of the 2016 European Championship, which kicks off at Stade de France on 10 June.
"It's not the first time and we need strong enough decisions to eradicate this," Blanc was quoted as saying by L'Equipe. "Not suppress it, eradicate it. You have to be very severe.
"Unfortunately, this happens at very high-profile matches. Do not think it is just Marseille, it happens at all grounds."
He added: "In six months, there is an important event. We must try to eradicate all of this but I think it will be very difficult.
"It seems that today, football grounds are the only place in society where people can go and do whatever they please. We will have to get tough."
