Gunnerblog is one of the most reasonable and measured fan/pundit/journalist in the world of Arsenal media.
And for what it's worth, I don't think he's wrong here, I just don't really care. I hate the Arteta (or Wenger) in or out stuff - I think it's reductive and I refuse to participate. I can't really be doing with the whole my side versus your side shit that goes on here and Gunnerblog is tapping into there.
I think what I think and it changes and develops all the time. I think Arteta is a far better manager than he has been given credit for thus far, and that now seems to be changing, but let's see what happens and how it all plays out.
