|2020–21 UEFA Nations League|
The first tournament began in September 2018, following the 2018 FIFA World Cup. The four group winners from League A qualified for the finals, played in Portugal in June 2019. Four nations, one from each League, also qualified for the UEFA Euro 2020 finals.
The competition largely replaces the international friendly matches previously played on the FIFA International Match Calendar to more competitive matches. The competition is regarded by UEFA as a major tournament.
