Even though Iceland have indeed surprised many football fans around the world when they managed to qualify for the last World Cup which was held in Russia, but it seems that it is quite a huge burden for Iceland to be playing in the Uefa Nations League being placed in League A, as Iceland have struggled to score goals against other teams and have also lost all their matches in the group. Maybe the players of Iceland would find it much better to play in League B after their relegation from League A.
I think you might be onto something.Even though I like Iceland,they might be overachieving in the last few years so for them League A was simply too much. League B seems more suitable in the long run. And if they are good enough, they will get back to League A.
