The Brazilian had a banana thrown at him by a spectator during the 3-2 win for his side but responded by eating it.
He insisted after the match that he had become used to such abuse, but has now called on Spain to stamp out the problem once and for all.
"There is a lot of racism [in Spain] towards foreigners," he told Radio Globo. "It's sold as a first world country but there are some things which are long overdue. FIFA should pay attention to such things."
Several footballers posted pictures of themselves on Twitter eating bananas as a message of support and Alves said he was overwhelmed by the incident.
"It was incredible. An action that was done without considering the consequences. The world is evolving and we must evolve with it."
