Concerning Gnarby, I didn't pay attention to any preseason stuff or much of last season, but from what i've seen, he looks a lot more promising, when he's attacking through the middle.
He has been effective through the center but it's tragic having a playmaker of Ozil's caliber and then sticking Ramsey and Jack on the wings, essentially crowding him out whilst offering absolutely no width, making us predictable and having no pace.
