Brazilian goal-scorer Neymar started an anti-racism campaign in response to the incident happened in Barcelona's 3-2 win at Villareal.
Neymar used the social media to kick off his 'we are all monkeys' campaign after a banana was thrown to Barcelona teammate Dani Alves in the match.
"We are all equal, we are all monkeys, say no to racism," he wrote on the social media site, accompanied with the hashtag #weareallmonkeys.
"It's a shame that there's such prejudice in 2014. It's time for people to raise their voices. My way of expressing my support is to do what Dani Alves did.
"If you think so too, take a picture of yourself eating a banana and we will use what they have against us to our advantage."
