Just been reading Arseblog and there were a couple of points/comments that rang true, although I'll also admit that my interpretation may not be what was meant.
Firstly perhaps NOT being in the CL may force the club as a whole to face the reality that we are NOT a top4/CL quality and we need to get to serious business if we want to regain that anytime soon. Time for the BS to stop deluding ourselves and for those in charge to walk the walk.
Second thing was the suggestion that Emery may have been a tactical appointment by the 3 horsemen as a quick fix/return for this season (based upon his tactical approach and Europa record & the disparity between our Home and Away form), while we still had the bulk of the squad to be more likely to do so. Now that Plan A has failed we have little choice but to now turn to Plan B, which likely includes a cull of the squad and potentially a reliance upon youth as part of a 3-5 year plan to regain top4/CL.
The question has been raised as to whether Emery is/should be the man for that approach, as he seems to prefer to work with players who are already fit for purpose. As such it is a valid question as to whether he should be replaced with a manager who has a better record working under such restrictions. IF Emery WAS recruited in regards to a 1 season opportunity as a 'quick fix type remedy' & having failed to deliver in circumstances thought to suit him, what has he got to warrant any continuation with a very different plan and circumstances?
Clubs that come to mind re their youth and development are Barca, Ajax, Monaco, Lyon and Sporting. The only one of those not in EUFA comps next season is Monaco. Jardim was shortlisted by many here to replace AW and despite their struggles this season Monaco have played some scintillating football under Jardim. I'm not one to change managers just because it didn't work out as intended, and perhaps we'd not be having this conversation if we hadn't suffered those season ending injuries mid season (if we'd possibly not dropped as many points trying to regain our feet etc). However if we are going with a new strategy and game plan to the one Emery may have been signed to, then IMO it is a valid question as to if he is the right man for that job.
EDIT - the obvious caveat to all this is that we do actually have a frakking plan to begin with. If not then we likely have some ways further to fall from grace.
