The play-offs of the UEFA Euro 2020 qualifying tournament decided the last four teams that qualified for the UEFA Euro 2020 final tournament, to be staged across Europe in June and July 2021.[1] Unlike previous editions, the participants of the play-offs were not decided based on results from the qualifying group stage. Instead, 16 teams that failed to qualify through their group were selected based on their performance in the 2018–19 UEFA Nations League. The sixteen teams were then divided into four paths, each containing four teams, with each play-off path featuring two single-leg semi-finals and one single-leg final. The four play-off path winners joined the twenty teams that had already qualified for UEFA Euro 2020.[2][3][4] The matches were originally scheduled for March 2020, but were postponed to 8 October and 12 November 2020 by UEFA due to the COVID-19 pandemic in Europe.[5][6]
