UEFA have warned Arsenal that they will face a backlash if their fans protest during their Europa League final with Chelsea next week.
Gunners supporters are livid after Henrikh Mkhitaryan decided against playing in the final in Baku over security fears.
The Armenian's safety was a concern because of the dispute between his country and Azerbaijan, the host nation of next week's fixture.
Despite receiving assurances aimed at allaying those fears, Mkhitaryan has chosen not to travel to Baku following discussions with the club and his family.
Arsenal boss Unai Emery said he respected the "personal" nature of Mkhitaryan's decision, but conceded it was "bad news" for his team.
And, according to the Daily Mail , there are concerns that Arsenal fans may make their feelings known with anti-UEFA banners and chanting.
UEFA officials will be keeping a close eye for any aforementioned protests, and will take action against the club if necessary.
The organisation has a history of charging clubs for any provocative messages, once taking action against Legia Warsaw.
The Polish club were fined £70,000 for a banner which showed a UEFA badge, a pig dressed in a suit and the words: “Because football doesn't matter, money does.”
Mkhitaryan said he was "hurt" to miss the showpiece event.
He tweeted: "It's the kind of game that doesn't come along very often for us players and I must admit, it hurts me a lot to miss it."
