Made my feelings known in a different thread regarding this.
For me it has to be Duncan Ferguson, he wants to manage, and I think his goal is to manage Everton one day, but he really should cut his teeth elsewhere. Why not us? I appreciate he has a lack of Managerial experience, but he's been coaching and learning under various Managers for many years now, again, I am an enormous believer in mentality, I think he'd have us fired up for a home game against a 3rd Division team in the early cup rounds as much as he would away to Rangers/Celtic. I don't believe for one minute he'd accept that our aim is 3rd and we should be happy with it, he'd demand and strive for better.
We all know what type of character he is, personally I find him infectious, passionate, heart on his sleeve and purely wants the best. He's a lot more level headed now but you still wouldn't fuck about with him, we need that, as well as someone with good tactical sense, he's learned from Moyes, Marco Silva and is now Ancelotti's assistant. The game where he was caretaker Manager and they beat Chelsea 3-1, you know they made more tackles in that game than they had done in 37 years? He's old school but has good teachers.
What he's done with a lot of the Everton youngsters as well, some of who still play for the 1st team, is highly regarded, It's just my opinion, I appreciate and accept that some will say " Fuck that " or maybe we couldn't afford him, but I genuinely believe he's exactly what we need. These 2 YT clips I have put up explain a bit about how he works.
