Sicario2 - Tier 1 what serious questions can you ask of a manager if he gets you to 89 points and, somehow, doesn't win the league? I'm not saying you can't ask questions, by the way, just - realistically - we wouldn't have done a lot wrong to get to that points total.
As Claudius has said, there has been a serious internal improvement at the club and I - I get there's always a tendency to want more - but when I think of the mood of this place when we blew 4th place two seasons ago and finished with 68(?) points... If I'd said to you then that in 2 years, the same manager would get us to 89 points, wouldn't you all have (rightly) thought me mad?
There are questions we can absolutely ask about Arteta - his squad management being one of them, but it can't be as binary as he wins the league this season or he goes mate. Not for me.
