So do I, but that's often why Director's of football (director of footballs'?) Stuart at a club long term to manage and keep the club on track to the owners values and hire managers to fit the team set up - which should mean that a manager won't need to overhaul the entire squad as they should be suitable to their brand of football to a certain extent.
I suppose this is where Tan comes in, with Acun very hands on in determining this as well so they should in theory be able to sign the players they want, for the style they want, and get a manager in who aligns with that. Then if that manager misses out on the playoffs on the last day of the season they can sack him and get someone else
