Its hard for him joining a new league half way through a season, but its even harder thats he's in and out of the team.
He needs a run of games to get properly up to speed and understand his team mates, unfortunately it is the business end of the season and we can't afford to bed people in, so for now he has to play a bit-part role.
Give him a full pre-season and slap him in the starting XI at the start of next season, give him a run of games and then we can judge him.
How people can rule him out as a waste of money now is a joke.
