A celebratory parade was held in Paris on Monday, with the members of Paris Saint-Germain, including former Galaxy star
According to Paris police commissioner Bernard Boucault, it took 800 police officers to contain the riot. There were 30 injuries and 21 arrests.
"The conclusion you can draw is that there won't be more any more events like this in a public place for Paris Saint-Germain," Boucault said.
"Today should have been a day of celebration for the city of Paris," the club said in a statement late Monday night. "The party was spoiled by a few hundred troublemakers who have nothing to do with football."
