Genoa's Serie A game with Siena on Sunday was suspended for 45 minutes due to crowd disturbances at the Stadio Luigi Ferraris.
A large group of Genoa fans accumulated around the tunnel area and threatened to invade the pitch early in the second half with their side 4-0 behind.
After a break of 20 minutes, the match officials and the Siena team left the field with the furious fans applauding them, but not letting the Genoa players approach.
Home captain Marco Rossi spoke with the group, who demanded the Genoa players took off their shirts before leaving the field.
After several more minutes, Rossi went round and collected his team mates' shirts, but Giuseppe Sculli refused to take his off and, with tears in his eyes, confronted the supporters, making it clear that he would not cave in to their demands.
A compromise appeared to be reached with the fans retreating from the tunnel and allowing the game to continue.
However, after the game, Genoa president Enrico Preziosi called for the fans who created the trouble to be jailed.
''I'm sorry that 60 or 100 people can say and do as they want with impunity without us having the ability to control them and send them home,'' Preziosi was quoted as saying by Gazzetta. ''They cannot take over the stadium and enforce their law. These people should go to jail, they are the evil of Genoa.''
Preziosi claimed he would prefer it if his side were now given a stadium ban.
''If today a child had suffered a ruptured eardrum what would happen?,'' he said. ''Do we have to wait for a dead man before putting them all in jail?
''I do not fear them. I hope we get a ban from playing at home, so we have to play away and get a bit of calm.''
Giancarlo Abete, the president of the Italian Football Federation, added: ''The events in Genoa are a very ugly incident which takes us backward and we must react.''
