German football club Bayern Munich is set to face disciplinary action by UEFA after fans unfurled a homophobic banner during a clash against Arsenal.

The banner featured the words ‘Gay Gunners’ and a sketch of Arsenal’s Mesut Ozil in front of the north London club’s cannon emblem.

It happened before Tuesday night’s match at the Allianz Arena in Munich.

The Telegraph reports Bayern Munich could be fined in the region of £50,000.

UEFA is expected to make an announcement this afternoon.

Arsenal Football Club’s LGBT supporters group, ‘Gay Gooners’ was established in early 2013.

Yesterday, former Arsenal defender Sol Campbell revealed sports clothing giant Puma were tempted to sign him on the incorrect assumption about his sexuality.

The 39-year-old said he was told of how Puma wanted to sign the “first gay footballer”.

Campbell, who is not gay, said the sport was also not ready to accept an openly gay professional player.

Retired Germany interntional Thomas Hitzlsperger announced he was gay in January.

Campbell said of Hitzlsperger: “He chose to say it now. He is not playing every week and going to stadiums – sometimes fans can be really vile.”
