To be honest, I don't see why we need another central midfielder (we have Canales, Parejo, Michel, Banega, Fuego, Romeu). That's two players per central midfield position. I don't know what the plan is with JDS but Real Sociedad also seems to be after the playmaker's signature. He seems to prefer Real Sociedad so that he can play Champions League football but seeing how close we came to signing his brother, anything can happen.
