Ramires and Matic should work well together, Matic is good at keeping possession and still a strong defensive midfielder, Ramires is one of the best box to box midfielders and wont be replaced as first choice anytime soon. Half the players meant to be "deep-lying playmakers" (Toure, Fernandhino, Martinez) are no more so then Matic is, and the players like Alonso and Pirlo who are, are either too small/weak or unavailable.
