Nations League 2026-27: How does promotion, relegation, knockouts and Euro 2028 work?

Once the Nations League campaign is concluded, all 54 competing nations will be ranked based on their performance in this edition of the competition.

That ranking will have a direct impact on qualification for the 2028 European Championships, being held in England, Scotland, Wales and the Republic of Ireland.

The Nations League ranking will also determine the seeding of nations for Euro 2028 qualification.

Regular qualifying will take place between March and November 2027, with play-offs for the remaining spots in the tournament to take place in March 2028.

As there are four co-hosts and none of them have been granted immediate qualification, the number of how many qualify will effectively determine how many play-off spots will be up for grabs.

Uefa have said that up to two places will be given to the best-ranked co-hosts that fail to qualify for the tournament via its primary qualification route.

Scenarios have already been designed for occurrences where either two, one or zero co-hosts are given entry spots.

Depending on which play-off format is required, either eight or 12 teams will enter.

A total of 24 teams will enter the European Championships, 20 of them will consist of the winners of the 12 qualifying groups and the eight best runners-up from those group.

The remaining runners-up will enter the play-offs, alongside the Nations League group winners from League A, League B and League C that failed to finish in the top two of their Euro 2028 qualifying group.

If extra teams are required, the best-ranked League D group winner will enter the play-offs.

Any additional play-off spots that become available after that will filter down to the next-highest ranked Nations League finishers until the play-off spots are filled.
