Napoli president Aurelio de Laurentiis has called for action after a violent day in Italian football.

For the Turin derby, the Juventus team bus had windows smashed and there were 11 injured Granata fans by a firework thrown by Bianconeri supporters into the stands.

ADL declared: "We need [Minister of the Interior Angelino] Alfano to take a good hard look at himself. I know he is worried about it, but he's far behind, because we already told him to give power to the police in the stands like they do in England. He didn't listen.

"This violence has nothing to do with organised fan groups. Dear Alfano, why do you want to wait for something an eight-year-old child could organise?

"We are tired of this inertia that guarantees political votes. In England the Prime Minister moved to fix violence in stadiums, while here everyone just stands around."
