I still don't understand. I, first of all, train for my team, then, if possible, i train for my U21/NT. For sure, training for my team isflexible and easier than keep an U21 player in roster ( less GS issue, less monoskill-primaries trainings and so on).
Then, being a first level U21 NT player (Italy/Spain/Russia/Poland for example) is very hard. Utopia should be considered at same level.
I'm managing Indonesia, and scouting ITA, at the start of 21yo season there are from 5 to 10 less levels in primaries. And indonesia was 14th in ranking, now is 25th... still very hard.
Another thing is: Utopia was added because local managers didn't want foreign users. That time BBs listen all and now try to add a NT in a "not-local and meltin pot" country? Very un-linear way to reason.
