So how did Mancini and Pellegrini win the PL with City then get binned off within a handful of years within each other? The saviour isn't a Russian roulette of managerial merry-go-round. It's a system that has to be aligned and functional from top to bottom independent of who the first team manager is. Was LVG and Jose not authoritative and respected figures who brought trophies to United? A clear vision, plan and execution isn't done in a year. It's done over a period of time, i.e. more than a few years, especially as it relates to United right now. Mancini and Pellegrini were recipients of a football brain trust formerly of Barcelona and a blank check....every single year. Then came Pep who elevated the team, which was already elevated to begin with. Nagelsmann or whoever can demand whatever they want, but it's already been shown that Woodward isn't afraid to renegade on his own words/actions. LVG 3 year contract, binned after year 2. Jose given a contract extension, binned shortly thereafter. United will not hired a full time manager until a director of football is hired, Ole given full time position and no director of football was hired. United have to be a self-sustaining football club where manager and player ins and outs do not cause a crater like crash in performance. I think it's extremely naive to say that one manager will come into town and turn everything around in short order at United. There must be long-term plan and vision that can sustain the ins and outs of managers, coaches and players, but that cannot start until you get the quality players and staff that allow you to grow and branch out from.
