Everton tried a lot of managers... You can see the results. Koeman, Ancelotti....etc.
If you aren't aware, Napoli came calling for Rafael twice during his Newcastle tenure, but he refused to ditch NU at that point of time.
Valencia regrets, Napoli regrets....
Having 7 teams above us in terms of quality and stability, and the only man who can take up the challenge and do better is Rafael. He can do better with a decent budget.
You want Jose, Ancelotti or Conte, you have to spend big bucks... Tuchel wants Haaland for 150mn. You want a younger manager, but they don't have the expertise, most of them were one season wonders.
