One thing I definitely believe he'll give us will be a bit more tactical nous in that position. It's no coincidence when we've signed him based on some of Rafa's comments about people applauding midfielders in that position (erm Colback) for doing loads of running based on his match stats, but in his belief when you're in that position you shouldn't be wasting your energy as to him that means you're out of position a lot, which has a knock on effect on everybody else.
