Scottish champion Celtic travelled on Tuesday to take on Ukrainian champion Shakhtar Donetsk in the UEFA Champions League (UCL) 2022-23. The teams settled for a 1-1 draw. However, the tie was marred with controversy involving the fans, as the visiting supporters disrespected the unfortunate demise of Her Majesty Queen Elizabeth II. A stand at the Polish Army Stadium in Warsaw hosting the away fans saw a fan being unfurled that read 'F*** the crown'. Naturally, it violated the Union of European Football Associations (UEFA's) disciplinary code, as the European body has launched disciplinary proceedings against the Scottish outfit.
