Absolutely, Klopp admitted in Germany his players stopped listening to him in the last year
However (and this is where most of the disagreement lies I suspect)
- SAF and Simeone were/are serial winners (with trophies in the closet) that earned them that right. I also believe none of those two had a run outside top 10 in their league.
- Somehow mythology has made Poch's top 4 and final appearances a false equivalence. Add
@Armchair Expert expert's point Poch has burnt a lot of his credit in the bank
But the answer is one of the following
- Refreshing the manager makes an instant change for all, club, players, fans
- Refreshing a few players is a longer term impact that may or may not work and creates an uncomfortable interim period where the "is it working" feeling is constant
- Change the manager and some of the player .. get the short and medium term impact
I don't see how the last option isn't the only possible logical answer, least risk option
