While the primary group phases are being revolutionised, UEFA are keen to preserve elements of the current system that have proven successful. The promotion and relegation play-offs will remain intact, ensuring a competitive bridge between the new leagues. The second-tier league will utilise three groups of six teams, or one of seven, to keep all member associations active. Crucially, the top-ranked teams in the top league will earn direct qualification to final tournaments, whilst the remaining spots will be determined through a high-stakes play-off system. This inclusive pathway guarantees that lower-ranked sides still retain a mathematical chance of reaching major international stages.
