Each team: Barcelona s Champions League match against Paris at home, about 2,700 fans of the away team went to Spain to watch the game

According to "Every Sport", Barcelona will play against Paris Saint-Germain at home in the Champions League stage, and 2,700 Paris fans are expected to go to Barcelona to watch the game.

Such competitions are usually classified as "high risk" events and security will deploy special measures to prevent any accidents on and off the field. Montphic Stadium will welcome more than 50,000 spectators, of which about 2,700 fans from Paris, whose tickets were sold out almost immediately after the release.

However, the security agency's biggest concern is the Paris extreme fan group Collectif Ultras Paris (CUP). Although the group has gone through some divisions in an attempt to clear out the more violent members, its relationship with Barcelona fans is not friendly.

In recent years, in European competitions, CUP has even issued a statement accusing Barcelona of receiving partiality, and in the past, when Boixos Nois was still active, there have been fierce clashes between the two Paris supporters in 2014.

To ensure that the fans of the two teams do not have direct contact, it is planned to monitor the buses taken by CUP members from the time they arrive in Barcelona until they return to Paris. In addition, special arrangements will be adopted at the scene to restrict the militants to specific areas and be surrounded by a large number of police forces.
