The Nations League was linked with European qualification for the 2024 FIFA World Cup, although to a lesser degree than the UEFA European Championship qualifying play-offs. The first round of the 2024 World Cup qualification consisted of ten groups, with each group winner directly qualified for the World Cup.
The winner of each of League A's groups goes on to play knockout fixtures to determine the UEFA Nations League champion. Below that, however, relegation and promotion come into play. The bottom-placed team in each group gets relegated to the league below, whilst the top-placed team gets promoted to the league above.
