Roma chief Bruno Conti has blasted Catania fans after Sunday's 1-1 draw in Sicily.
"The window of our coach was broken and we were spat at and insulted. You can't go from the hotel to the stadium without a huge escort of cars.
"How can you play a game of football when you think that you might not be able to leave the stadium?
"What is this, a war? We're supposed to be talking about a sport. I'm worried about the future of calcio for the children who come to watch games. Something has to change."
