You have two types of manager really. The first is a coach who has a specific style of play they want implemented that they take from club to club and stick to that approach. Pep, Klopp, Pochettino are all the best examples of this. The 2nd are more flexible managers, who will adapt to different approaches. Ancelotti, Mourinho etc are good examples of this.
I don't think it's a better or worse scenario, but I would say certain managers suit certain clubs. It also tends to be, more experienced managers tend to fall into the latter category.
I think we've needed a manager like Ancelotti, who is able to look at the squad, forget about how he wants to play and do whats best fr the team.Michael Keane, for example goes from looking like a championship player to an international player based on where you defend. The aforementioned 4 attacking players like playing on the break. We have developed an approach to suit the squad, rather than the other way. No amount of coaching will make Keane comfortable high up the pitch.
While it's controversial, arguably the best manager in terms of results of the last 4 was Allardyce, who was cut from the same cloth. Allardyce was incredibly dislikeable though, couldn't work under a DOF to a medium term plan and wanted to spend copious amounts of money on poor players, but I do think he was tactically flexible. He saw it was a poor squad, and developed a plan to play defensively and try to nick games by the odd goal.
The thing is, Ancelotti is a much more likeable person and has won a lot more, so his pragmatism will be roundly accepted. And for where we are it makes sense.
