You have signed Nikola Saric (17) from Herfølge BK in Denmark. He is supposed to be the our biggest striker talent in Denmark since Bendtner who is still quite young. Every big club wanted him, so I guess you're lucky to have him in your squad/reserves. He snubbed a move to Barca when he was 15, and about to turn 16.
I don't think he cost you that much. Maybe 500.000 £
Here's a couple of youtube videos of him. (Herfølge vs Bayern München)
