Manchester United fans have been warned they will be kept behind in the Olympic Stadium for 90 minutes after the end of Wednesday's Champions League quarter-final with Roma.
Although United have expressed reservations about the move, local police
believe it is necessary to prevent trouble between the two sets of supporters.
Mindful such a lengthy wait could cause problems amongst their own
4,000-strong travelling contingent, United plan to show club videos on big
screens inside the stadium once the home fans have departed.
Supporters have been warned of the delay in a letter from United with has been
sent out with match tickets.
The club have also passed on more specific information warning of the dangers
of travelling independently to the stadium, advising that supporters of other
English teams have experienced major safety problems due to the violent
behaviour of the local 'ultras'.
According to the letter, of particular danger are the metro trains to the
Piazza Flaminio, the Ponte Nenni bridge and also the Campo de Fiori.
The game is the first involving a British team in Italy since Serie A was
suspended following the death of a policeman following the Sicilian derby
between Catania and Palermo in February.
