Not to be insensitive, but you have no idea what your doing. Since you haven't even played this game for a week yet, look at learning how to shape, train, and maintain your own team before you look at trying to manage a national team. If in a season or two, you are still a dedicated manager who is doing a good job with your team, then I would support you trying to run a national team, like a micro-nation U21 team.
