NYON, Switzerland: Bayern Munich and Celtic were fined by UEFA on Friday for fans showing banners judged to be offensive at Champions League games.

Bayern fans spelled out an expletive on a pitch-side barrier fence to protest the 70 euros ($72) ticket price they had to pay at the stadium of Czech opponent Viktoria Plzeň on Oct. 12.

That’s the maximum price traveling fans can be charged to attend a Champions League game since UEFA set the limit three years ago.

UEFA fined Bayern 15,000 euros ($15,500) for a disciplinary charge of a “provocative message of an offensive nature.”

Celtic were fined 17,500 euros ($18,000) for the club’s second disciplinary case this season of displaying a slogan opposing the British monarchy.

The banner at a home game against Leipzig on Oct. 11 read: “Against hunger and the crown.”

Celtic have historic links to the republican movement in Ireland and many fans traditionally oppose the British monarchy.
