"There were 13 serious mistakes by the referee," Mourinho told the post-match news conference at the Bernabeu while waving a piece of paper with the incidents typed on them.
"I don't feel under pressure when I am doing what I like doing, and I like to coach. I am tired of this. My team needs to be defended. If I say what I think, I will be on the front pages tomorrow and I will be suspended.
"There is a club and a structure and I want them to defend my team from there."
"I have a good personal relationship with the club, even though we think differently," he added
The Portuguese has already served a two-match ban for being sent off in the King's Cup after showing contempt to a referee, and picked up another ban in the Champions League.
"The game was forgettable," Mourinho said. "It was too ugly. I wouldn't have paid anything to watch it. At home, I would have put on Eurosport to watch one in Vietnam."
