The fight that took place on Thursday evening between OGC Nice and Paris Saint-Germain (PSG) supporters in Paris is not a new incident. Various clashes have occurred between the supporters of these two clubs in the past. The fight happened in the center of Paris, resulting in 6 people injured and 65 detained. One of the injured is in serious condition. It is stated that the hostility between the supporters stems more from political and social differences than from sporting rivalry. For example, in 2003, during a Nice-PSG match, a Paris supporter was stabbed, and other supporters were taken to the hospital. In 2022, before the French Cup final, a fight broke out between Nice and Paris supporters in the city, and a few people were slightly injured. In September of the same year, during a match between Nice and Cologne, the presence of Paris supporters among German fans led to violent incidents. These events show that the tension between the supporters of the two clubs is not limited to competition on the field. Further research is needed for more details and background on the fight.
