Real Madrid coach Carlo Ancelotti supports the partial stadium ban for Valencia.
The Mestalla's Mario Kempes stand has been ordered shut for the next five games after racial abuse targeting Vinicius Jr on Sunday.
Ancelotti said, "An awful lot has happened in general over the last couple of days. Society at large, not just sport, has accepted its guilty conscience a little bit. It could be a real opportunity.
"They have imposed measures these days that affect the stands at Mestalla. It's a very important step in the right direction and I hope this issue can be resolved as soon as possible.
“I'm not asking anything of anyone. Everyone should behave as they wish to behave, taking into account that certain things can be done and others should not be."
