For a lot of that we were also "inverting" our full backs that left us massively exposed, they both play wider now so I don't think the defensive woes are down to Ramsey's inclusion (he does more running than Robinson as well). In Ramsey's 6 games we also went away to Leeds, Ipswich and Leicester who were responsible for 7 of the 10 goals we conceded with him in the side so there's plenty of context for our early poor defensive record
I think we do play too defensively and are lacking a striker. None of Meite, Etete or Ugbo are good enough to play up there on their own consistently.
