Agreed. I would put him in the 'raw' category. He must be talented though, but we have yet to see it as fans.
Once thing I will say and this is why I hate threads like this is that he is a young guy, away from home wanting to do well. He must have friends and family that he wants to make proud. He is not playing awful on purpose.
The money spent on him is irrelevant IMO, he needs a bit of time to get his confidence back as there is a player in there somewhere, but he is trying too hard with no confidence to back it up. There is only two ways this will go IMO; he will learn and grow from it and become a good forward, or he will shrink away, ruined by the experience. I hope it is not the latter - not only because we need him, but on a human level. We have to remember that regardless of pay etc, these are young kids out there and human beings.
