He added: “It was important to us to establish an awareness concept during the Euros in order to make the experience and attendance of our Euro 2024 events even safer.”

Simon Harris, a veteran member of the England Supporters Travel Club and a Conservative member of Shropshire Council, told Telegraph Sport: “If you’re in a bar and you’ve got a whole raft of Serbian hooligans threatening you, Panama’s going to be the last thing you’re thinking of. It would be getting out quick, I would think.
“Will they be warning you that there may be foul language, or flashing lights, or something else that might trigger you? At what stage do you say, ‘Do you know what? If you can’t hack it, don’t go’.”
Meanwhile, police have suggested it would be better for fans coming to Gelsenkirchen for Sunday’s game to smoke cannabis than drink alcohol.
The Class B drug was legalised in Germany on April 1, although it will not be allowed inside the 62,000-seat Veltins Arena, nor in fan zones, bars or city squares.
