Don't listen to Mr. Glass what he said made no sense. I would not say your player has NO chance to make the U21 National Team for the US. He will need to have no injuries and at least a level 4 trainer though to have a decent chance. I would suggest you talk to the U21 manager Rambo VT
(22884). I would try to help you, but I am not experienced in training small forwards, and want you to get the best advice.
Best of Luck
