It's like having a new contractor joining you as a colleague at your work, you don't want to get too friendly or excited because you know he's only here for a short while. So hello this winters Carlos Alcatraz!
A CB that has poor positioning, can't tackle, can't read the game and can't pass but is an excellent dribbler, that's not alarming me at all. You will fit right in.
He's young so it is a very sensible move for him to get a few months of tactical football where he has a larger chance to play due to lack of competition in the squad.
