Inter Milan boss Roberto Mancini has called for more action to stamp out fans violence.

It's been confirmed a paper bomb was thrown by Juventus fans into Torino rivals on Sunday, injuring 11 people.

"Even in England these situations occur sometimes, but not as frequently," he said in a pre-match Press conference ahead of Inter's trip to Udinese on Tuesday.

"In England however, within 24 hours the police arrest the culprits. Unfortunately for us, we talk about it for years. Serious measures need to be taken."
