Bless him, he just is not good enough. You can see natural ability very quickly, an he has not got it. No one really knows anything about him but the team/management will soon realise that he is in the wrong league. Lucky he was free!
Why are you so sure of this?
He's played all of 2 minutes. While he doesn't have the physique of a traditional footballer, and a rather obscure past experience, to write him off before he watching him given a decent run is moronic.
