I think with Herrera, Schweinsteiger, (hopefully) Periera and Carrick (for a year), our passing/dictating from midfield might be fine. And Schneiderlin sorts out the tackling midfielder area. We lack a midfielder with skill and pace even more IMO. Someone like what we wanted Anderson to be. Someone like what Toure does for City. The midfielder who can make a driving run from deep and take opposition midfielders/defenders out of the game.
In fact, that's what we lack throughout the team. Players like Martial who pick the ball up and just have time and that ability to lose their man with a bit of class.
