The European National League will be held in the following form: 55 teams will be divided into four grades according to the ranking, and the first grade standard (A, B, C, D) will be determined according to the points ranking of UEFA associations.
Eu promotion rules.
The top teams of the four A-level groups participated in the semi-finals (semi-finals, three or four finals and finals) and decided the champion in June of the following year. The teams at the bottom of the four groups were relegated to the B-level league. The top four teams in the B-level League will be promoted to the A-level League, and so on. In addition, the UEFA National League is also linked to the number of participants in the European Cup finals. The four levels of the UEFA National League will produce four places to advance to the European Cup finals. Specifically, the top four teams at all levels who failed to advance through the European preliminaries can play off to determine a promotion quota.
