As part of the various events planned by the Collectif Ultras Paris (CUP) for the second leg of the Champions League semi-finals between Paris-Saint-Germain and Borussia Dortmund, the ultras were planning to carry out a fireworks display at the crossroads of the Anciens-Combattants in Boulogne-Billancourt while the players’ bus passed in the direction of the Parc des Princes, located a few hundred meters away meters away.
They gave up, according to police sources, fearing that other less identified supporters would join the operation and that they might lose control, for which they could be blamed. The Paris Police Prefecture was informed of the project and did not oppose it. The CUP has planned a very big and beautiful cheer on three stands in Auteuil, Paris and Boulogne.
