In the post-match press conference after the 1-0 win over Sevilla, Mourinho asked the Madrid hierarchy to do more to help him defend the team with regards refereeing performances.
But Perez said last night: "It's customary for the club not to speak about the referees, and what we had to say has already been said by Jorge Valdano, who is our spokesman and best represents the image of our club. Now we need to look to the future.
"What happened (with Mourinho) was nothing major and we shouldn't give it any more importance. This is a solid and strong institution, with a great image that little incidents cannot tarnish."
