In comments to Trofo, wiss and DireWolf.
I might not get my understanding correct about Nations League but actually even if England get relegated it does not prevent them from progressing, since the group winners are the ones who progress, could it be that actually relegation to B means they might get easier opponents? And extra chance for World Cup?
Or is it only possible to do so from Group A?
I tried to read but confuses me even more. Some reports say win or lose the tournament does not mean anything except for the cup which is like a Charity Shield.
