**The 2026-27 UEFA Nations League League A features 16 teams split into four groups of four, with each side playing six matches through September and November.** Due to the upcoming reduction to three leagues of 18 teams for 2028-29, relegation rules have been adjusted: only the two worst fourth-placed teams are automatically relegated to League B, while the two best third-placed sides stay up automatically and the remaining third- and fourth-placed teams enter March 2027 promotion/relegation play-offs against League B runners-up. After four matchdays, Turkey, Czechia, Serbia, and Norway sit at the foot of their groups with limited points, while Croatia and Wales occupy third places under pressure. The final two rounds in November will set the exact relegation candidates and playoff participants, with current form, goal difference, and head-to-head results among the lower teams likely proving decisive in determining the two automatic dropouts.
