We say it every year, but if ever there was a season where we needed top 4, it's this one.
Imagine if Allegri is willing to sack off Juve and poised to take over the club that's finished 4th then 3rd then 2nd in England and hoping to push on and maybe prove it's possible to do well in Europe and also prove his Juve success wasn't just having the best team, then gets cold feet about the reality of taking over a club in 5th/6th place, losing it's top players who want to be in the CL and then playing the "get into the top 4" game for the next 2 years? If modern coaches look at being at a club for 3-4 years, that might be a turn off for them.
You could maybe argue that Juve to Arsenal last year would have been a bit of a sideways move, but if we're 5th or 6th it's kind of like taking the Liverpool job at any time in the last 5 years. They're a "big club" with plenty of "history" and not afraid to spend a bit of money if needed so it should have ticked plenty of boxes, but nobody really wanted that job until an unemployed Klopp was offered it mid season.
We can still get a good coach and we're still an upwards move for most coaches, but maybe we won't have our pick of anybody. I'm starting to agree with the people that think we're heading for a few years of being a mess and I'm not sure what type of coach would be best for that.
