Bayern Munich may be punished by UEFA after the club’s fans protested the price of tickets for a group stage match against Anderlecht.

Fans displayed an “illicit banner” and threw around fake money, prompting UEFA to open disciplinary procedures.

The fans held banners during Wednesday’s game saying, “Are your necks not full? Is your greed now finally satisfied?”

A Bayern fan group, Club Nr. 12, issued a statement on the day of the game saying Anderlecht had made 85 percent of the tickets available to the German club’s fans priced at 100 euros ($118).

“Even by the standards of the generally high-priced Champions League, this represents a new dimension for a first-round game,” said the statement, which thanked Bayern for supplementing the tickets so fans had could pay 70 euros ($82.50).

The case will be dealt with by UEFA’s Control, Ethics and Disciplinary Body on December 7.
