Raheem Sterling and Kyle Walker received racist abuse on social media shortly after Manchester City’s 1-0 defeat by Chelsea in the Champions League final.
A number of monkey emojis were posted on both players’ Instagram profiles following the final whistle at the Estadio do Dragao on Saturday evening.
Sky Sports News has contacted Facebook, which owns Instagram, for a response to the abuse.
Sterling has been subjected to online abuse on several occasions, including earlier in May following City’s Champions League semi-final win over Paris Saint-Germain.
That incident came just two days after the sporting community engaged in a weekend-long social media boycott where broadcasters, clubs, teams and players came off their platforms in protest over rising levels of discrimination.
