sorry to speak on a forum that is not my own country, but you are right KwaiWah, this player should be removed. I doubt anyone will buy him for 600k and I doubt he will get any training.
As a former U21 coach, as U21 coach I would try and speak with the owner off the player and ask what his plans are for this player.
This is a very nice player, and would be a waist to see get lost... Maybe he will never play for the U21 team, but he might have a chance to enter the NT if he gets proper training.
We have the same problem in England as I am sure you have and other small countries too. There arent many (active) teams thus not so many good players in the draft and than to see them end up like this is a real pitty...
