I think I'm missing something here.
Did he say he'd 'prefer' to qualify via the traditional route or that he didn't want to do it through the nations league route?
If it's the former, I don't see the issue, the traditional route is the earliest opportunity we have to qualify and would be a bigger achievement, why wouldn't you rather do it that way?
If the nations league semi/final was happening say next month and he was saying 'nah f**k that I want to do it the proper way' then obviously that would be lunacy.
