Competitive games replace friendly matches\n\n The purpose of creating the Nations League was therefore to replace the majority of those matches and although the fixture calendar is busier than ever, competitive games are at least far preferable to non-competitive ones for most.

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.
