Hi
Not sure where to put this, but here goes.
Filip Jörgensen and Matt O'Riley refuse to represent the Danish national team. Both players are born in other countries than Denmark, but have chosen to play for the Danish national team.
Matt O'Riley was even in the squad for the previous Denmark game against San Marino - https://www.transfermarkt.com/danemark/startseite/verein/3436
Filip Jörgensen has made the switch from Sweden to Denmark official with the 'Change of association'. By doing this, the decision can never be reversed making it impossible for Jörgensen to represent Swedish national team. However, in the game he becomes a national team player for Sweden.
