#3 There is a winner to be crowned at the end
The winners of all groups of 3 in League A will fight in a 4-nation tournament at the end of the Nations League.
There will be a promotion and relegation system where the teams from lower leagues can enter the higher leagues and the teams not performing well in the higher leagues will be relegated to the lower leagues.
The winners of the four groups in League A will play each other in a one-leg semi-final in June 2019, with the winners going forward to contest the final.
And the winner of the final will be crowned the UEFA Nations League champions.
