Maxi Gomez was deemed to have interfered with play as Raphael Varane deflected the ball into the path of Rodrigo from Carlos Soler's pass.
"It's always the same, always the same!!" shouted captain Dani Parejo.
"But what's it about?!" screamed another.
Players lined up on the side of the pitch as ref Jose Antonio Sanchez Martinez reviewed the footage, forcing him to shoo players away.
"It's clear!" said a Real Madrid player in the stands.
In the end, Sanchez Martinez awarded an offside and ruled out the goal.
"But what offside?!" asked a frustrated Jose Gaya, who saw a yellow card for his complaints.
"Give it up already, man," he said.
"It doesn't affect me, Sergio, it doesn't influence me at all," referee Sanchez Martinez responded.
