Real Madrid manager Rafa Benitez believes there is a "campaign" against him and the the club.
A number of polls in Spanish media have indicated fans would like to see Benitez, 55, replaced at the Bernabeu.
His side go into Wednesday's meeting with Real Sociedad third in La Liga, two points behind leaders Barcelona who have a game in hand on their rivals.
"Everything that is open to criticism is criticised and that which is not is manipulated," Benitez told reporters.
"What is clear is that there is a campaign against Florentino Perez, against Real Madrid and against the manager.
"Surveys are carried out continuously and the media's interest in doing them is part of their interest in manipulating things".
Spanish publications AS and Marca conducted polls in which Zinedine Zidane - currently coach of Real Madrid's second string - was the clear first choice to manage Los Blancos.
