Yes. Because Real don't hire managers, they hire head coaches whose task is to work with what they have. Real Madrid teams identity and personality come from the name and brand itself and the fact that no club in the world can compete with them when it comes to attract the very best players in the world. Their model is unique and the closest club that tried to replicate it was Abramovic's Chelsea, but nobody else functions like them.
Mourinho and Capello are protagonist managers. Hiring both of them was seen at the time as against the grain for the club. It came at a time when they were going through a bad spell especially in the case of Mourinho and desperately needed a "savior" to stop losing to Barcelona.
The others are not protagonist type of managers by any means. They are facilitators who don't impose a strong personality or playing identity on their teams. Del Bosque was the same for Spain when he allowed the strong Barcelona core to dictate the way of playing whereas Ancelotti is the dream head coach of an organisation that wants a diplomat who will know how to handle the board, the ego of big names and steer the ship with minimum personal input in terms of their own ideologie or vision.
I generally disagree with this. Yes, Real consistently buy the best players. But so do PSG, Barca and to some extent, Chelsea. And yes, these teams do compete on players, though I agree with you, Real has a natural advantage.
What you are saying is that Real tends not to hire strictly ideological coaches/managers. Really, there’s only a few modern managers that fit that profile — Pep, Klopp, Enrique and perhaps Mourinho and Simeone. Most managers/coaches are pragmatists. IMHO, the pragmatist is more a “manager” and the idealist more of a “head coach”. Pep is famous for micromanaging even simple passing sequences.
If you are defining a “protagonist” as a manager that has a notable personality, I suppose you’d be correct in that Zidane and Ancelotti seem bland compared to Klopp or Pep. But both Zidane and Ancelotti carry as much respect, perhaps more, than Klopp and Pep and I don’t think their control over the squad is any less than Klopp or Pep.
This worship and glorification of the idealist(Klopp/Pep) vs the pragmatist is ridiculous. Why are they held in higher regard than Zidane and Ancelotti? Certainly the latter two have an equal or even better record than the former. The latter do not require expensive complete squad turnovers. They are masters at getting the most from the ingredients on hand.
In our case, why is it necessary to hire in the next idealist as a manager? Like Real, we have great spending power. We are one of the richest clubs. We should be buying the best talent, both a youth and senior level, and bringing in the best managers, all the while not allowing standards to drop.
