PSG fan stabbed in overnight clashes in Milan ahead of Champions League
The victim was stabbed twice in the leg and taken to Milan's Policlinico hospital for treatment, police said. Italian media said he was a 34-year-old Frenchman.
He was injured when a group of around 50 Milan fans clashed with visiting PSG supporters shortly after midnight in the city's canal district, a popular spot for nightlife.
Two police officers were also hurt after police baton-charged the French fans to try to restore order.
"Football for us is passion, not hate. Sport is supposed to unite, not divide," the club said in a post on social media site X, the message written in English, Italian and French.
