check this out:
Mathijs Schrijvers is one of my internationals in te dutch team. Semi finals he played against Spain.
Now the final is coming up against England, and the guy is just out of my team?
Vanished! He still plays for his own team, but he is out of the squad?

Very strange indeed.
You still have 23 players so who is the player that wasn’t selected at all?

Btw. Friso Rijvers, can he still stand on his feet with stamina 18 :)

I have no idea, selection changes where closed ofcourse so i can’t have removed one at all.
And Rijvers….yes that’s bad…but for international games stamina doesnt count right?

Correct, stamina doesn’t count for national squad matches. Not sure how he could have vanished from your team. As you mentioned once the competitions start the selection changes are locked :-/
