If this was before he went to Barca, people here would be fapping to death at the thought of signing him. Now all of a sudden, he's not good enough.
I agree, perhaps he's not 100% optimal. But he's really close and there are alot of redeeming qualities that he brings. Chemistry with Vidal and Isla. Familiarity with Serie A and Italy - therefore, quick and seamless integration hopefully. Brings a much needed element to our counter-attacking setup when we choose to use one. And he fits our style with his work rate. And even though he's not prolific, it's very possible, almost probable that he will increase our goal output from the SS position.
