I think there are four types of good managers in roughly two groups.
Those that can galvanise a team to scrap for every point, keep things tight, play the percentages and look for any way of getting a result.
If they can also spot a player, build a team and refresh it when required with sensible signings then they are a very good manager.
These managers can do very well but simply don't have the funds to buy or charisma to work with the types of players who ultimately win the big games.
Moyes with us is probably the best example of that type.
Lesser versions are your Allardyce, Dyche, Pulis, Koeman types.
Then you have the managers with charisma and/or tactical know-how.
So the likes of Mourinho and Simeone tend to build "us against the world" mentalities, have the personality to work with star players, but tactically aren't that different from the above group.
Then you have the "philosophy" types which come in the lesser role of Martinez, Rodgers, probably Tuchel at the moment (but superior to the first two) and most of the up and coming German coaches.
and the top group of Pep Guardiola, Wenger (mainly a decade or so back), Pochettino (probably similar to Tuchel) etc
What we need is a coherent choice of a manager given the long term view of how we want to play and what types of players we are after.
If we go for an Allardyce now (and let him at the money in Jan) and a Tuchel type in the summer we are in danger of doing a Palace and trying to switch styles with a squad not suited to it.
