Nothing great about substituting one useless player with another. I don't see the point in acquiring a moody, mentally fragile and weak individual and hoping he somehow transforms his game. After all, we acquired promising individuals in the past for them to fail miserably.
Case in point: Martinez and Motta last year. They were supposed to be doing well for their former clubs, and look how that turned out.
If we acquire Elia, it just goes to show that all this talk of quality over quantity is pure BS by our incompetent sporting director.
