Real Madrid TV have a history releasing videos highlighting referee's errors, the latest being Sanchez Martinez who will be the referee for Saturday's clash.
Flick is now the latest coach to express displeasure with their rivals' antics and revealed what he told his players about the officials.
"I didn't know about the Real Madrid TV videos, it's not right that this is done," Flick
"The referees have a very hard job, and my job is to prepare the players. I have a great deal of experience and have never had problems with referees.
"I told the team at the beginning of the season that the focus should be on performance, not on referees.
"We can't be with these things, but with the energy at full throttle and focus on our performance."
