On Potter
We all love our respective clubs and put them on a pedestal - every club's fans are guilty of this. "Oh let's just get XYZ", "Why don't we go and sign ABC"?
Everton, at the moment, are not a very attractive prospect for an ambitious manager like Graham Potter. I know it hurts to read this, given Everton's history and "big club status", but as of right now little Brighton are a much better run club, with (arguably) a better playing squad and undeniably a business model.
Potter has not had a failure in his career so far, and Everton's managerial history recently has been dire. Benitez (18 months), Ancelotti (18 months), Marco Silva (19 months), Allardyce (7 months), Koeman (16 months).
Potter has 100% job security at little Brighton, where the main priority is staying in the division. He has an unblemished record and has made it very clear he wants to manage the biggest club(s) in the world. He is unlikely to want to spend 18 months at Everton, get sacked, then have to rebuild his reputation at "another Brighton".
In short, Potter will eventually go to a much bigger club than Brighton, but there is absolutely zero chance it will be Everton.
I think it will be Niko Kovac (no compensation needed), or Rooney (to "compensate" having a Kopite as manager, bring in a former player and appease the fans).
