UEFA is warning Arsenal fans against staging any protests regarding the Henrikh Mkhitaryan situation.
The Armenian attacker is not traveling with the Gunners for the Europa League final against Chelsea.
It is due to the fact the final is taking place in Azerbaijan, given there are many tensions and travel restrictions between the two countries.
However, UEFA officials will be eager to stamp out any protests from Gunners supporters who are attending the final in Baku, per The Mirror.
UEFA has a history of fining clubs if they are unhappy at supporter protests in the stadium.
For instance, Legia Warsaw were fined after their fans had a banner with a UEFA badge, a big dressed in a fancy suit and the phrase: "Because football doesn't matter, money does."
