Wasn't talking about him specifically but in general, loads of hopeful kids who move across Europe who are richer for the experience but have their lives messed up in the process, I know several where it happened that way. Obviously it's a risk for everyone from Cesc to Möller but in cases where the club never really believes in the kid it's pretty irresponsible to do it.
Often enough it's a risk worth taking, remember how Bellerin was supposed to be just the sidekick to the bigger talent in Toral (who's playing in Crete these days), but for cases like this surely you'll find some kid in North London to fill Möller's role
