Heh, I suppose you aren't following much, because on Monday, the USA U21 just beat Poland to win the overall U21 Worlds.
As I told you i do not follow U21, so all my comments are about senior national teams. USA beating poland on u21 means nearly nothing, there are tons of NT players that are not balanced enough to play in u21, players trained to make the most of elastic effect. And the mayority of u21 players cap before making it to the senior nt.
My believe still stands, you dont need to agree nor I need you to, but with same GS/enthusiasm and without HCA there is no NT that can beat poland. (and in the same conditions there are 4 or 6 teams better than USA)
