Juve fans stabbed before Supercoppa
ANSA says the incident happened in the afternoon, near the Stadio Olimpico, before the start of the match and that both men were from Rome.
The two fans, aged 27 and 28, were taken to Rome's Policlinico Gemelli, with stab wounds to their backside. They will reportedly need about a month to recover.
