On one hand i have not at any point had any expectation of this season being any different thus why i find the histrionics so bizarre, it seems that people seem to become so angry because they've convinced themselves that it's going to be different.
The way i look at it, I haven't seen any evidence in how we play that we can handle the pressure of expectation or that we have the guile to put teams like Spurs or Mourinho managed sides to bed.
You can take the game individually or you can take the game as an ominous portent of what's to come, if we lose to United and to PSG which I happen to suspect we will than the atmosphere becomes mutinous again, and if the familiar collapse happens again in February/March (that often coincides with the Champions League knock-out phases) than i think what we saw in March and April will happen again only i suspect more intensely.
I think whatever the club's hierarchy say, I don't think they will want this kind of situation dragging on constantly as it looks bad and I do believe that Wenger is managing for his Arsenal future - and that top 4 won't be good enough....only a sustained title challenge and improvement in the Champions League will especially as he has spent a lot in the summer.
