Someone needs to break down this concept of "pressure" to me. Who is applying the pressure at Madrid/Barcelona? Why can't it just be ignored?
It is not direct pressure, such as ultras visiting the dressing room (as happened with Sevilla) but the fact that the football debate disappears to focus on whether he is valid for the job and who will be his possible replacement.
The certainty that he has to win something every year , because it is something that has always been demanded, because of the stature of the club that he knows and always looking sideways at what Madrid does, and viceversa (if Madrid were bad everything would be different).
Press conferences that are "is this game your last chance?", "have you lost control of the team?", "what do you think of Sport's cover about your replacement?".
In the end, this insistence of the press makes a dent in the fans or the players themselves who see that they will end up being harmed.
In more extreme cases such as Benítez or Martino, are the players themselves who leak that the coach is useless, which ends up causing a murky atmosphere.
This also has repercussions on board-coach relations, with more ambiguous public support.
I suppose that if Florentino and Laporta were owners they could put aside everything external but they are elected and coaches are shields in bad times and personal successes in good times.
