UEFA is changing the format: The Nations League will be divided into three divisions starting from the 2028 season.
Starting from the 2028/29 season, the Nations League will be divided into three divisions, with each division having 18 teams. This is official.

ℹ The leagues will consist of three groups, each with 6 teams. Each team will play 6 matches against 5 different opponents.

However, with 55 teams participating, Group C will have 7 teams. Their schedule will start one season earlier.
