Conte's current system doesn't require 200 iq footballers in the midfield. They are like almost wasted there. At least in the mezzala role. It doesn't even add too much added benefit if you are a 200 iq footballer. This is the thing with Eriksen and the current system. It doesn't take enough out of Eriksen.
Maybe next season we can be better if we can get a proper preseason and train more different penetration models which uses Eriksen's ability more effectively (what .h. suggested few posts above).
