The average tenure of football managers these days is 18 months. Sometimes you'd wonder if most people here are still back in the Moyes days when Davey held the post for 11 years simply because Bill couldn't afford a better manager - nor a worse one.
If the director of football is truly influential, you can sack the manager twice a year and still maintain stability.
It is extremely unlikely that the next Everton manager will be at the club in five years time. If he is, it's probably because he's a plodder who has no better options and is doing just enough to hold on to his post because we can't afford to fund a better manager. If we could lure a top manager now, it doesn't matter if he'll be gone in 18 months. The statistical likelihood is that he will be gone one way or the other: of his own volition, like Carlo, or sacked like Koeman, Allardyce and Silva. What we need is to get somebody who leaves us in a demonstrably better position after departure. Carlo didn't really succeed there - he moved us from 12th to 10th - so there is a sense that we have stood still.
One thing's for sure. This current squad needs serious surgery. Any new manager needs to ruthlessly purge the inadequates - of whom there are many. Anyone looking to "assess" the playing staff should have his CV binned. That's Brands's job.
As Everton give us no excitement on the pitch, I, for one, am looking forward to hounding the next man out of his job before the turn of 2023. Summer transfer windows and managerial searches have been my main highlights of the last 5 years. Why would any sane Evertonian deny himself the pleasure of dismissing Eddie Howe, David Moyes, and sundry managerial detritus every 18 months? We've nothing else to become exercised over.
PS I'm expecting a surprisingly ambitious appointment.
