Think if the U21s had been playing meaningful games he may well have got moved up but as U21 games this month are friendlies I can see why SFA have left him with the U19s for the qualifiers. I am happy enough with him playing as it will give him experience of playing against different styles of players over the next week which can only be of a benefit for the player and the Dons in the long run. Also international apperances help the compo figure when he leaves on a free at the end of his deal.
Edit: Meant to add that its a pity U19 game is at Hamilton tomorrow as would have headed over to see how he gets on if it had been at Falkirk like the rest of the games.
