The UEFA Nations League is a biennial international football competition contested by the senior men's national teams of the member associations of UEFA, the sport's European governing body. 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, will also qualify for the UEFA Euro 2020 finals. The competition largely replaces the international friendly matches previously played on the FIFA International Match Calendar.
