England stars, Bukayo Saka, Marcus Rashford and Jadon Sancho suffered racist online abuse following the Euro 2020 final loss to Italy.
Rashford, Sancho and Saka all failed from the spot on Sunday night as England went down 3-2 on penalties.
The trio’s social media pages were quickly flooded with racist comments, leading the FA to release a statement condemning the “disgusting behaviour”.
A spokesperson said: “The FA strongly condemns all forms of discrimination and is appalled by the online racism that has been aimed at some of our England players on social media.
“We could not be clearer that anyone behind such disgusting behaviour is not welcome in following the team. We will do all we can to support the players affected while urging the toughest punishments possible for anyone responsible.
“We will continue to do everything we can to stamp discrimination out of the game, but we implore the government to act quickly and bring in the appropriate legislation so this abuse has real life consequences.
“Social media companies need to step up and take accountability and action to ban abusers from their platforms, gather evidence that can lead to prosecution and support making their platforms free from this type of hateful abuse.”
The Metropolitan Police also condemned the “unacceptable” abuse, adding it will be investigating the “offensive and racist” social media posts.
The force said in a statement on Twitter: “We are aware of a number of offensive and racist social media comments being directed towards footballers following the #Euro2020 final.
“This abuse is totally unacceptable; it will not be tolerated and it will be investigated.”
The official Twitter account for the England men’s and women’s national teams offered support to the victimised players.
It said in a statement: “We’re disgusted that some of our squad – who have given everything for the shirt this summer – have been subjected to discriminatory abuse online after tonight’s game.
“We stand with our players.”
England missed the chance to end a 55-year wait for a major trophy after Sunday’s match with Italy.
