There has been violent clashes between Parma and Juve ultras outside the Tardini.
EDIT: A group of 50 Juve ultras armed with belts and sticks (lol) went to storm the bar that Parma fans drink at near the stadium, the owner managed to close the shutters in time, but the Juve ultras chucked bins and metal barriers at the front of place and a couple of Parma fans were injured. Riot police had to intervene.
