Jose Mourinho accused Real Madrid of lacking fight and looking unhappy against Barcelona on Saturday, just as the pressure cranked up on coach Santiago Solari after a second successive Clasico defeat.
Mourinho has been among those mentioned as a possible replacement for Solari, as Madrid have been knocked out of both the Copa del Rey and, realistically, La Liga's title race within four days.
"I think it was not a happy performance," Mourinho said as a pundit for bEIN Sports. "It was not the performance of a happy team, of a team with great belief and self-esteem.
"Clearly they are now in a zone after a few bad results, especially after the cup match, where they are in a low. They couldn't bring to the game what I used to call the temperature of the big matches. They were passive.
"I cannot speak about a bad performance, it is just a soft performance. Sometimes you play like this against medium teams and in the end, you get a positive result, but against the top teams you have to do a lot more than this if you want to win."
Former Real Madrid president Roman Calderon has claimed Mourinho will take over in the summer.
"I'm pretty sure he has general information about the club of his passion," Mourinho said. "But he knows more than me because I know absolutely nothing about it at all."
