Look at Chelsea success... look at Real... they rotate thru managers all the time. Certainly not the "United Way", but clearly it is not automatically "counter productive".
Now then our issue.
I have a simple theory...
the manager has lost the dressing room. I mean honestly if you are Herrera or Mata how can you see Rooney at CM and Falcao and RvP continually getting starts while you sit on the bench. Sorry if I was in their boots I would lose faith with the guy. same thing with Pogba, he saw two defenders start CM over him under Fergie.
One of the managers most important jobs is to make you feel important and frankly i think way too many of the players have no idea what he wants and therefore have no way of feeling vital to the team's success.
All these people focused on tactics and formations (and I have a fair few of those to my name) really just want players playing in positions they feel comfortable in and are natural. Much of that is just assumed in thye FIFA generation, but frankly this is what Fergie was a master of, man management and I would bet in private conversations more that a few current players would *not* be signing LvG's praises...
