Lega Serie A President Maurizio Beretta fears the hooligans are winning in Italy over stadium closures.

"With these latest sanctions we risk handing the stadium keys and the regularity of the tournament to tiny trouble-making groups," said Beretta.
"This is penalising the rights of thousands and thousands of real fans."
