Xhaka obtained the certificate in 2022 while playing for Arsenal, stating that he was in a state of emotional turmoil at the time. He expressed serious reservations about the COVID-19 vaccine and felt a deep distrust of it, which led him to make the decision. Xhaka has since apologised for his actions and accepted full responsibility, stating that he is prepared to cooperate fully with the authorities. The Swiss Football Federation has reached an agreement with Xhaka, deciding that it is in the best interest of the team for him to miss the upcoming matches in the League of Nations. The Swiss team is set to play three matches against Macedonia, Scotland, and Slovenia between September and October.
