The UEFA Nations League is a biennial international football competition organized by the Union of European Football Associations (UEFA). It was first introduced in 2018 as a way to replace international friendly matches with more competitive fixtures and provide an additional pathway to qualify for the UEFA European Championship.
The tournament features national teams from the member associations of UEFA, divided into four leagues based on their UEFA coefficient rankings. Each league is further divided into groups, and teams within each group play against each other in a round-robin format.
The Nations League offers promotion and relegation between leagues, with the top teams from each group in the lower leagues earning promotion to the higher league for the next edition, while the bottom teams are relegated. It also provides a secondary opportunity to qualify for the European Championship through the playoffs.
The competition consists of two stages: the group stage and the finals. In the group stage, teams compete in a series of home and away matches within their group. The group winners from League A advance to the finals, where they compete for the title of Nations League champion. The finals include semifinals, a third-place match, and a final.
The Nations League has been well-received as it adds more meaning and excitement to international fixtures outside major tournaments. It allows teams to face opponents of similar skill levels and provides a competitive environment for players and coaches to prepare for major international tournaments.
