West Brom defender Semi Ajayi was the victim of racist abuse on social media after Sunday's Premier League defeat by Liverpool.
Ajayi wrote on his Instagram account: "Yet again, I come on Instagram to more racial abuse after a game.
"Instagram sort it out."
In April, Instagram announced a tool to enable users to automatically filter out abusive messages from those they do not follow on the platform.
Facebook "urges" people to make use of the safety features which it says "can meaningfully decrease the abuse people experience".
"No single thing will fix this challenge overnight but we're committed to doing what we can to keep our community safe from abuse," the social media company said.
