I think it shows how fan perception clouds a lot of things.
Ancelotti was absolutely hero worshipped by the fanbase yet he was one of the worst fits possible.
Benitez on the other hand is hated by many yet is the closest thing we've had to a Moyes/Royle type manager which is exactly the type we need to put some effort back into the current squad and build some solid foundations.
You look at what Moyes has done at West Ham and he's turned a team buying over priced primadonnas like Anderson and Lanzini waltzing around on big wages and now has them a tough outfit who gives most teams a game these days.
Thats exactly what we need from Benitez over the next 1-2 seasons. Fans simply need to give him time and give him 1-2 summers to rebuild the squad.
Make no mistake the road we have been going down was heading for eventual relegation make no mistake about it - hiring and firing managers every 18 months, a squad of overpaid wasters turning up when they felt like it we've needed to press the reset button since Koemans disaster 2nd season but have dragged it on and on.
