Real Madrid chief Emilio Butragueno had no complaints after their home defeat to Atletico Madrid.
Real fans jeered their players at the final whistle and Butragueno can understand the frustration.
"The fans were very motivated. They filled the ground and created a special atmosphere, but the team has not been good. So the audience were unhappy.
"But this support is very loyal," argued Butragueno.
"Every three days there is a test and an opportunity to improve. And that is what we must do."
