People will probably think this is ridiculous given the general opinion of Joe's distribution but isn't there a chance that Joe could perform that sweeper/keeper role if he is given license to do it and absolutely knows that it is his role to have a starting position which is further forward? He has a decent first touch and despite the general wisdom being that he can't pass, I generally think he looks confident on the ball and it is often the options (or lack of) that are available to him that is as big an issue as anything. I think what is expected from him in terms of distribution could be entirely different. I'd be surprised if he is expected to repeatedly play pin point, high balls to Aguero or Sagna under Pep.
