Judging by the profile on wikopedia ( for what it'sworth ) he might be a good prospect as you say. Seems like people feel he has the talent so needs the right environment or coaching, mentor, kick up the ass or whatever to improve. maybe another Ojaama ? McCall does seem to have a knack for getting the best out of players. However, having said that it comes down to the player in the end and if he really wants to get better or not. Sounds like a gamble and McCall will have to weight that up. We did'nt bet much on Ojaama and got a great return for the money plus some great benefit to the team.
But somehow "Silva the portugese winger" is more appealing than "Jack Smith from Airdrie"
