I used to go to footbal regularly while living in Italy, either Fidelis Andria in Serie C2 as they were, or Roma in Serie A. I also saw Chievo play (I exclude them from this general statement on the point).
Italian football was literally saved by the World Cup win. With crowds in decline and the game swept by corruption people were fast losing interest. It was therefore becoming controlled almost by ultras.
I have witnessed absolutely disgraceful behaviour at matches, nazi salutes, throwing bottles into areas where families were sat, fans fighting for no visible reason, flares being thrown onto the pitch, bangers being let off where people are sat or stood. The list is endless. The first time I went to see Roma I was shocked and scared. I was caught up in a riot and was lucky to get out of the way. Some of the material on open display is illegal at best, inflammatory and politically reprehensible at worst. I have seen people searched entering grounds but not their bags
, nobody arrested, and probably (in its own way) worst of all, police and stewards LET ALL OF THIS HAPPEN before their very eyes.
OK, what can they do, but the fact is, nobody has done more than the odd thing to stop all of this. I'm amazed there hasn't been worse far sooner.
I've also met ultras who openly support Liverpool (and Liverpool fans, please don't get this out of context, it's not my view I'm expressing here) because they admire them for killing Juventini at Heysel. I was so sickened by this had it been Roma fans I would be ashamed to play under my username now.
Basically, this will take time, but it has to be sorted, and finally they are doing something about it. I wish them luck!
