I still think Carvalho can be of great use to us.He's a fast defender and none of our other top 3 are. Having a pair of slow CBs may costs us against a top team,it might work in the league but in Europe it does matter. If Terry wasn't who he is and didn't mean so much for the club I'd try pairing Alex or Ivanovic with Carvalho to see how that works,now since he's literally undroppable I believe the understanding he and Carvalho have should be used. Our central defence is much better and "deeper" than those Arsenal or ManU have,thus even if Ricky moves to Milan we'll be in a good position.
