Barcelona fans were spotted with a banner with a Nazi reference during their Champions League match at AS Monaco on Thursday evening. The black banner read “Flick heil” in white lettering, in a reference to the Nazi salute “Sieg heil” (“hail victory”). The banner was shown during the game broadcast at streaming service DAZN and was criticized by social media users. European ruling body UEFA was asked for a statement on the matter on Friday. Barcelona lost the match 2-1.
