Would there not be the chance of problems with fans being dumped in odd places late at night?
When we were in Rome we were held back so long. We came out of the ground and found that there were no coaches waiting to take us back to the city centre. Me and my mate decided to walk. Along with a group of about 20-30 we started heading in, what we thought was, the right direction. After about 10mins walking we came to a large crossroads where another fan was running towards us. He also had decided to walk, he was now being chased, or had been chased. We all headed back to the ground where we found that the coaches had eventually turned up. By the time we got to the station in the centre it was about 2am, all the Italians were asleep, and getting a taxi was a nightmare.
In Turin a couple of years ago we got held in the ground for ages. When we finally got out we were put onto buses. As we were about to pull away from the ground the bus in front of ours got attacked. The police strolled over, not in much of a hurry to baton their own, and told the crowd of Juve fans to, basically, 'go away'. We were hurtled at high speed with a police escort through the town to the main station near the city centre. As soon as we got there fans fled away in taxis or to the trains, me, I could see my hotel from where we were dropped off. It was only about 20-30 yards away, and made a run for it. There were a few Italians hanging around, but not many, as again it was gone 1am, and the thing about these grounds is they are outside the centre, and those few hours after the game the police had already cleared the central areas, and who really wants to wait till 1-2 o'clock in the morning just to have a scrap and possibly nicked?
But one thing that is true if your caught in the wrong place, whatever time of day they will have a go. I have found that train stations are not a good place to be stranded at. In Turin the night before the game a Liverpool fan was having a drink at the station bar when a group of Juve fans came into the bar and gave him a bloody good hiding. It made the news the following day, and they had apparently caught some of the offenders, but never did hear what happened to them, probably got let off!!
Don't let this put anyone off by the way, just remember to be sensible AND respect their culture. To be honest of all the times i've been abroad with the Reds we are very well behaved, but as in all walks of life you do get the odd dickhead!!
