Not sure what your point is. We changed the chief exec, apart from that first summer I think Woodward has done great. Probably overseen more transfers in three years than Gill did in seven.
The point is that there's a distinct difference between a manager here and a coach at Real, Barca, Bayern, etc. It's not just nomenclature. The chief exec here is responsible for the business side of operations. His main involvement on the football side is to broker transfers and contracts, but the manager is the one primarily responsible for identifying who the club chooses to pursue and who the club chooses to extend, let go, etc. At Real, Barca, Bayern, Dortmund, Atletico, PSG, and Juventus, the coach is responsible for coaching the first team and providing input on those other decisions, but the burden for those decisions (and most other high-level football decisions) rest on the head of an upper management staff (sporting director/director of football and the rest of footballing operations). Those positions tend to be more stable than coaches, because they're the ones who drive the organization's long-term philosophy through player recruitment and turnover, youth development, etc.
The reason why those teams can change coaches without missing a beat is because the coach's first and foremost responsibility is coaching the first-team in accordance with the philosophy pursued by the football operations folks. The organizational philosophy doesn't change with a coaching change...the only thing that changes is how that message is delivered to the first team and who delivers it.
Compare that to United. Our footballing philosophy changes with every manager change, because the manager drives organizational philosophy (all that shit that most clubs have an entire staff to oversee) in addition to coaching the first team. As a result, every time this club changes managers, you end up overhauling far more than Real, Barca, Bayern, Dortmund, Atletico, PSG and Juventus do when they change coaches.
In the Bundesliga thread,
someone posed a question to the Dortmund supporters on this forum: Would you rather keep Tuchel or Sven Mislintat (their chief scout). The answer was Mislintat easily, because they have enough faith in their football operations team (Watzke, Zorc, etc.) to find another coach capable of delivering their message, but finding a chief scout able to identify the quality of players that Mislintat has brought in for them is exponentially more difficult. Imagine if you asked United fans if they would rather keep Mourinho or Jim Lawlor. Would most United supporters even know who Jim Lawlor is?
As far as the number of transfers overseen by Woodward, the number of transfers executed shouldn't be used to gauge how this club has performed in the transfer market or how Woodward has performed. The actual performance of those transfers, or the surplus value derived from those transfers are far more significant.
