No guarantees they come in and do things right. Actually taking into account historical information it's likely to take us further away from where we need to be.
What I will say is changing for the sake of changing is a root cause why we are in a mess. Only if there are people available who have a plan and will create a stable long-term upturn we should act. Perhaps we missed the boat with Rangnick...
I believe there are lots of managers who are better than Benitez. I don't believe there are many worse fits for Everton than a has-been red like Benitez. The fact people are still not willing to accept this after our worst run in 22 years, makes me wonder what on earth is going on.
Changing manager is not a problem. It's 2021 and good teams change manager all the time, it's not a big deal at all. It's totally normal and all the managers sacked already this year were sacked for less than our run of form.
I want Lampard or Potter ideally. I want a long term plan, with no over 25s signed for significant money of say £10m or more. Our only chance is finding the next top manager before they make a name for themselves and are established. The same goes for players. Any more signings of older players past their peak need to only be on low wages and on free transfers. Why was Benitez allowed to sign Townsend and Rondon when our squad was already far too old?
