It is meant to visually demonstrate the double-headed eagle, the main image on the Albanian flag.
[1] This gesture is often performed by players of the Albania national football team to celebrate a goal or at the end of a victorious game.
[4] In the 2018 FIFA World Cup, Swiss players of Kosovan descent Xherdan Shaqiri and Granit Xhaka and Swiss player Stephan Lichtsteiner, performed the gesture in a match against Serbia and were subsequently fined by FIFA "for unsporting behaviour contrary to the principles of fair-play".
[5][6][7][8] In a similar incident during the UEFA Euro 2024 Championship's Serbia–England match, Kosovar journalist Arlind Sadiku directed the gesture at Serbian fans while on a live broadcast; UEFA revoked Sadiku's Euro 2024 media accreditation pass several days later.
The image went viral in Albania and Greece, being well-received in the former but causing controversy in the latter.
