We can't sign both Caceres and Alex right , since we only have one non-EU place, unless either one of them having an EU passport. I think Caceres, is a signing for depth. He will be our 5th defender, someone who can cover any holes in the defense in the even of an first choice player getting injured. He's going to do what Ivanovic does for Chelsea, what Zabaleta does for Man City,Bonera for Milan. We need some good cover on the bench as well, especially when its clear that Conte doesn't want Motta or De Ceglie anywhere near the team. I think both of them will be sold sooner rather than later.
