It all looks rather complicated.

The interesting bit is where it says "The overall Nations League rankings will determine the composition of the draw pots for the subsequent European qualifiers". Group B winners get promoted, so I'm guessing that means if we can win our group in League B, we'll be in a better position than if we finished bottom of a group in League A. We aren't likely to win a group in League A and gain qualification that way, so doing well in League B might be better for us in terms of seedings than doing badly in League A.

Or have I misinterpreted the whole thing?
