Sadly I fear that unless we have an Evertonian in charge any manager we have dill have this attitude. It's probably only Redknapp out of the current managers who recognise Everton as a significant force in football, the rest have now grown up weened on a diet of Liverpool/United/Chelsea. They are unable to tap into the psyche of the Everton supporter. Moyes was bewildered why uscfans wanted better than 5th or to win at places like Old Trafford. Koeman is the same, he thinks we're privileged just to have him and if he bores us into 7th then he'll see it as job done because in his eyes we have no right to expect higher.
Any manager who comes in and starts doing well will have the Martinez effect. That first season when he had stuff to prove, so did Lukaku, so did Barkley, it was great. Then all of a sudden everyone treated us like a stepping stone, Lukaku Stones Barkley all had eyes for other places, Martinez was being touted for Arsenal or Barca. A club can't operate this way and be successful, half the squad think they're too good for the club, the other half resent the players who are only playing for themselves.
It can't help the harmony in the squad when every man and his dog knows that Koeman thinks he's too good to be here and as soon as he does anything if more he'll be off.
I really think to get back to winning, after Koeman goes (not that I'm advocating this now) we need someone 100% commited to the club. Not someone who has a dream to manage United or Barcelona or grew up in awe of Liverpool. We need someone who realises the peak of their career will becrrsurrrcting Everton, who gives out a message to the players and the media that he is here to win. We can't have another stepping stone manager who thinks he's doing us a favour. As soon as Moyes/Martinez/Koeman thought they'd proven themselves enough and that we owed them for being here they went down the pan. We need someone who recognises that it is a privilege to manage us and that they have to strive for the best all the time. I genuinely think we need someone from this parish but it could work if the right manager was out there and got taken in by us.
