The Portuguese coach has reportedly decided not to speak to the press until the end of the season, with the exception of games in Europe's premier competition
The former Chelsea and Inter boss already missed the press conferences surrounding Madrid's league games against Valencia and Atletico Madrid, and assistant coach Aitor Karanka looks set to continue to take his place at media gatherings for the remainder of the current campaign.
Madrid only recently ended a media blackout which had been imposed in the wake of their controversial draw with Villarreal at El Madrigal on March 21, yet Mourinho has no intention of speaking with the press again ahead or before Liga games.
Meanwhile, Sporting boss Javier Clemente has taken a leaf out of Mourinho's book by refusing to speak to the press ahead of this weekend's Primera Division clash with Real Madrid, too.
The Rojiblancos announced on their official website that not only will the Liga strugglers train behind closed doors at El Molinon on Friday, their coach has decided against giving any interviews before travelling to the Spanish capital as well.
It now seems likely that neither of the coaches involved in the game at the Santiago Bernabeu will face the media beforehand.
Los Blancos' meeting with Sporting gets underway at 20.00CET on Saturday.
