The 2026–27 UEFA Nations League A league phase opens later this month with 16 teams in four groups of four, where the bottom side in each group is directly relegated to League B for 2028–29. Newly promoted sides Czech Republic, England, Greece, Norway, Turkey, and Wales enter after strong 2024–25 results in League B, facing established powers such as France, Germany, Spain, Portugal, and the Netherlands in pre-drawn groups that set up tough tests for several newcomers. Turkey, Greece, Czech Republic, and Wales appear in the bottom slots of their respective groups on the schedule, while third-placed teams will contest home-and-away relegation play-offs against League B runners-up in March 2027. Recent national-team form, squad depth, and home/away results across the September, October, and November matchdays will shape final standings.
