Barcelona's encounter with Inter Milan was marked in red. Barca have to win to stay in with a realistic chance of making the knockout changes of the Championas League.
To avoid a repeat of what happened in the match against Eintracht Frankfurt in the Europa League last season, Barcelona took measures to make sure most of the fans were Barca ones.
It is for that reason that all fans were asked to carry their Spanish ID card or passport with them to make sure the name matched that of the ticket.
However, three supporters were refused entry despite having a ticket for the clash and a copy of the documentation on their mobile phones. The authorities did not let them enter.
