I don't really disagree with any of this.
This season we are about where most people thought we would/should be. There's been inconsistency, some really good results and some really poor ones. We knew about some of the glaring weaknesses in the team/squad that weren't addressed in the summer and they've not gone away. Equally some of the signings have worked out, one or two haven't and some we've barely seen (the last bit is still my biggest gripe this season).
Next season is the one that makes or breaks it though, for me at least.
If he's given a reasonable amount of money to spend, most people would (I think) be hoping for a European place next season. That's actually quite a task, given your traditional top 6 will presumably get their acts together, then Villa and possibly Newcastle will be there or thereabouts and you have the added problem of the really well-run Brentford, Bournemouth and Brighton.
European qualification next season will probably be a fair old ask, but I think it's one we have to be demanding as we need to keep improving.
As disappointing as it is for us to be probably missing out on Europe this season, having been within touching distance, I don't have a problem with finishing 10th - it's about where we should be right now IMO.
Next season, the demands will be bigger and I think we'll need an exceptionally good transfer window if he's going to be able to deliver on those demands.
