**Switzerland, Northern Ireland, Austria, and Sweden currently lead their respective League B groups after four matchdays in the 2026/27 UEFA Nations League, positioning them as frontrunners for direct promotion as the four group winners advance automatically to League A.** The adjusted promotion/relegation rules for this cycle—designed to transition toward three 18-team leagues in 2028/29—mean the group winners earn straightforward promotion, while runners-up enter A/B play-offs against select League A sides. Recent results, including Switzerland’s strong start and Austria’s consistent performances, have shaped these standings, with the final two matchdays in November 2026 set to decide the outcomes amid remaining fixtures across the groups. Trader consensus reflects these on-pitch developments and the limited time left in the league phase.
