legitmate question - how do you find the transfer market for a polish player being affected by the number of polish users?
ie: More users = more trainee's = greater supply = lower prices?
and the other theory being that, there is only one U21 side. In a small country, you have more chance of your crappy player being in the U21 team, so on the transfer market, a worse player may sell for more, compared to a larger market, where you may have an awesome player, but there are 10 others like him.
Or is it just not like that in reality?
