Exactly my thoughts, and I had posts about that. My point was about identification.
If there was a manager out there that with Everton past and was a good manager, then fair enough. Carsley comes closest, but I have none that really convinces me. But as I said Rooney for me is a worse manager than Dyche. And he had his chance in a few clubs now.
Three of the best managers in the league are born in my region that is less populated than Liverpool Urban area. Unai, Andoni, Arteta. Also Lopetegui or Alonso come from here. I suggested some names that I think could move a club forward, and also speak English, which I say is a criterium for me.
I want a manager that has experience in a good league, maybe build up a good team before and implemented philosophy. Well yeah, there are examples like Arteta or Maresca that were assistants before only and became good managers, but there are also many examples of assistants of a world class manager that failed to become a good manager themselves.
