The UEFA Nations League is an international European football competition for the senior men's national teams of UEFA member associations. It was created to replace meaningless international friendlies by providing more competitive matches between teams of similar ranking. The competition features a league system with promotion and relegation across four leagues (A, B, C, and D), with teams playing home and away matches in groups. The winners of League A groups advance to a final tournament to determine the overall champion. The Nations League also offers an additional pathway to qualify for major tournaments like the UEFA European Championship. The tournament runs every two years, with the league phase spread over international breaks in September, October, and November, followed by knockout rounds and finals in the subsequent year. The current format involves 16 teams in Leagues A, B, and C, and 7 teams in League D.
