The 2026/27 UEFA Nations League A features a modified relegation format tied to the shift to three leagues in 2028/29. Only the two lowest-ranked fourth-placed teams across the four groups face automatic relegation to League B, while the two best third-placed sides stay up automatically. The two worst third-placed teams and two best fourth-placed teams enter home-and-away play-offs against League B runners-up in March 2027, with aggregate score deciding survival. As of early October, fourth-placed sides include Turkey, Czech Republic, and Serbia on zero points, alongside Norway on three; third-placed teams sit between three and six points. The final two matchdays in November will set the precise rankings before play-offs.
