Starting point is consistently appointing managers who have over performed at every club they've managed and preferably had a track record of winning trophies. We've not done that for past thirty years. Perhaps we should try it?!
Last 10 years, managers who have won titles/trophies in England:
Arteta - staying
Slot - high variance...could be sacked early next season or they could challenge at top of table
Pep - retiring?
Klopp - nope
Conte - at Napoli, wouldn't come here
Ranieri - out of coaching
Glasner - tough to say...might listen to an offer from the Friedkins?
ten Hag - supposed to work for Twente next season...probably not a better manager than
Moyes!
Rodgers - nope
Howe - could be fired in the summer or early next season, but either way, not leaving for a new club
Hard to find proven managers willing to change their jobs for any other club, let alone one that would come manage Everton.
