Manchester City defender Kyle Walker has called for more to be done to prevent online abuse after he revealed a "vile, racist and threatening" message he received in the wake of Wednesday's 2-0 loss at Juventus.
Walker played the whole match in Turin but could not help Pep Guardiola's team avoid a seventh defeat in 10 matches.
England international Walker posted a screenshot of a message he received on Instagram from an unnamed user to his social media accounts on Thursday, which read: "Bro you can **** around and die you stupid ass *****."
"No one should ever be subjected to the sort of vile, racist and threatening abuse I have received online since last night's match," Walker wrote on his X and Instagram accounts.
"Instagram and the authorities need to stop this happening for the sake of all who are suffering this abuse. It is never acceptable.
"To our fans, we will continue to work as a team to do better, to improve and to turn the corner together."
Sky Sports News has contacted Meta, owner of the social media site, for comment.
City quickly condemned the racist attack. A club statement read: "Manchester City strongly condemns the racist abuse that Kyle Walker was subject to online following last night's fixture.
"We refuse to tolerate discrimination of any kind, regardless of whether that be in stadiums or online.
"We will be offering Kyle our full support following the disgusting treatment he has received."
A Premier League statement read: "The Premier League condemns all forms of discrimination. Racism has no place in our game or anywhere in society. We encourage anyone who hears or sees discriminatory abuse to report it so action can be taken.
"The Premier League will support Kyle Walker and the club to tackle online hate."
Kick It Out said in a statement: "It's absolutely disgraceful to see the racist and threatening abuse Kyle Walker was subjected to following Man City's Champions League match last night. This incident once again exposes just how deep this issue runs online.
"With reports of online discrimination to Kick It Out more than doubling last season and platforms failing to act decisively, we stand firmly behind Kyle's call for social media companies and authorities to do more.
"Accountability and action are urgently needed, starting now, not just when the Online Safety Act comes into effect. We're working closely with Ofcom and stakeholders to make sure that when the Act does come into force starting next year, it protects players and fans alike.
"If you see it or hear it, report it."
