Bayern Munich could find themselves in hot water after some of their supporters unfurled a homophobic banner before last night's Champions League clash with Arsenal.

The banner had 'Gay Gunners' written on it as well as a less than flattering caricature of Arsenal midfielder Mesut Ozil in front of the club's signature cannon.

Although the banner was reasonably small, Bayern could still face a heavy fine from Uefa if previous incidents have set a precedent.

European football's governing body have confirmed they are looking into the matter. Chief of press Pedro Pinto wrote on Twitter: "There will be news from Uefa on the matter this afternoon."

Celtic were slapped with a £42,000 fine after their fans unveiled a huge display during their group game with AC Milan.

The 'illicit banner' featured images of William Wallace and Bobby Sands as well as the message: "The terrorist or the dreamer? The savage or the brave? Depends whose vote you are trying to catch or whose face you’re trying to save."

Celtic have also been on the receiving end of a controversial banner, during their group stage clash with Ajax earlier this year.

The Dutch club were later fined £21,000 for the sectarian messages displayed by sections of their supporters.
