You've justified all 5 of those positions pretty well, given the context of the situation at the time.
The reason I always ask is because I absolutely refute the idea that Ole is operating in isolation. Mike Phelan has won the Premier League (I think 3 times?) with United. And probably operated as the key tactical person in SAF's operation during that time.
I'm not saying they're tactical geniuses or anything but this idea of "naivety" is too simple. Pep would look just as, if not more, naive with this squad.
The issue is that most people can't see that context and would rather change manager than to be patient with the current team.
100% there is a team involved and for sure Phelan has a lot of knowledge. I think he is more involved in the coaching than the tactics but usually they go together.
Comparisons to other managers and teams are really pointless in my opinion. The closest you get is Arsenal now (only one change in manager so more consistency, but squad quality similar), and Liverpool when Klopp joined. At United, you have a squad restrictively built by 4 managers, with businessmen almost making the on field performances a lottery because they really dont need the squad to perform in order to make money.
