The 2026-27 UEFA Nations League begins on Thursday, featuring teams competing in four divisions. Each nation aims for promotion and the chance to qualify for major tournaments, although direct qualification through the Nations League is not possible. The top teams in League A will advance to the quarter-finals, while group winners in lower leagues will be promoted.
The competition runs from September to November, with teams playing home and away matches. The knockout stages will culminate in June 2027, and the best-performing teams not qualifying for the 2028 European Championships will enter play-offs for final spots.
