Bayern Munich have been fined EUR20,000 after fans threw fake notes on the pitch during a Champions League clash with Anderlecht last month.
Supporters threw rolls of mock-up EUR500 bills at the Constant Vanden Stock Stadium in protest against the high cost of tickets.
They also held a banner apparently criticising UEFA for their pricing policy, which read: 'Is your grEUREURd now finally satisfied?'.
Travelling fans were angered after some reportedly paid as much as EUR100 for match tickets.
European football's governing body has decided to fine them after they were charged with throwing objects and displaying illicit banners.
Spartak Moscow have also been fined EUR3,000 for setting off fireworks in their draw with Maribor.
