The FC Barcelona board was very clear from the day it was announced that Eintracht Frankfurt would be returning to the Camp Nou that the shameful scene of 2022 would not be repeated.

On that occasion, 30,000 Germans were able to enter the Barça stadium for a Europa League match, even putting the safety of Barça members at risk. Barça was also eliminated from the competition that night.
The club has been determined to combat ticket scalping and is doing so firmly, knowing that Eintracht fans are experts at circumventing any obstacle. Therefore, Barça decided that only members could purchase tickets for this match and that the German club could only distribute 5% of its allocated tickets to its fans, as stipulated by UEFA regulations.
Despite this, Barça already had strong indications this Saturday that 323 members had resold their purchased tickets and that seven Spotify Camp Nou season ticket holders had done so with their season tickets. For now, the club has opted to cancel these tickets and has informed the members who allegedly intended to profit from them. They also warn that if the resale is confirmed, the case will be referred to the Disciplinary Committee and could result in the member's expulsion.
The club has also made it clear that next Tuesday there will be thorough checks at Spotify Camp Nou to verify that the tickets belong to the people entering the stadium. Therefore, they have asked everyone attending the match to bring their ID. They are aware that German fans often enter the stadium wearing the home team's jersey and then reveal their Eintracht Frankfurt jersey once inside.
