We should in theory have done enough to play in some sort of nations league play off.

20 teams qualify for euros automatically
In league of nations
12 teams are in league A
12 are in league B
15 in C
16vin D
So let's say 10 from league A qualify
And 7 from league B
Then 3 from C

That leaves 2 from league A who didn't in their play off
5 from league B in the play off
12 from league C and 16 from D

So starting from D you get 4 winners then C then B Then A

When you get to A there are 2 spaces left so in league B there is another team available so they are selected . That leaves 0 teams in B so we then go to C who get another team who him into the play off. Therefore in theory if all of A automatically qualify probably better off finishing lower.

In respect to the next nations league for world cup there is no qualifying planned but once world.cup increased they are looking to do a similar thing but only for teams in top 2 leagues. So 2 spaces available.
