The 2026–27 UEFA Nations League A league phase opens September 24 with four groups of four, where the fourth-placed side in each faces automatic relegation to League B while third place enters March 2027 promotion/relegation play-offs. Turkey joins France, Italy and Belgium in Group 1; Greece lines up against Germany, Netherlands and Serbia in Group 2; Czechia meets Spain, Croatia and England in Group 3; and Wales faces Portugal, Denmark and Norway in Group 4. These four promoted sides from the prior cycle are widely viewed by traders as the clearest underdogs based on squad depth, recent qualifying results and historical head-to-head records against established League A sides. Early injury updates, including absences for key players such as Belgium’s Thibaut Courtois, add minor variance but have not shifted overall group hierarchies.
