I think it's been really enjoyable to get a peep behind the curtain - with the acknowledgement it isn't really likely to change strongly held opinions about Arteta, Edu and our squad.
That said, for me, as someone who probably was an Arteta sceptic a year ago, I do think this series makes it very clear that Arteta is far from the grim faced robot he usually presents to the media - and that encourages me. There's a really telling line in one of the early episodes from Edu who says something like - Once he starts building relationships within the team we'll go boom, because tactically he is top.
And I think that this is where we're getting to now.
I didn't even find reliving Spurs & Newcastle that painful really. We didn't qualify for the CL because we weren't quite ready to do it and I've made my peace with that. We've added genuine quality (and apparently a couple of big personalities) to the squad now, the team has the pain of losing out - and to that lot of all teams - last season. I believe it will drive them on to better things this year.
My only complaint about All Or Nothing really, is that it didn't take place the year before, because I would have loved to have been a fly on the wall during the Willian debacle!
