Bernardo Silva has been charged with misconduct by the Football Association
The Portuguese tweeted an image of a young Benjamin Mendy alongside an image of the brand mascot of Spanish confectionery brand Conguitos on September 22.
He deleted the post, which has now led to an FA charge.
A statement from the governing body on Wednesday morning read: "Bernardo Silva has been charged with misconduct for a breach of FA Rule E3 in relation to a social media post on September 22, 2019.
"It is alleged that the Manchester City player's activity breaches FA Rule E3(1) as it was insulting and/or improper and/or brought the game into disrepute."Page 2: 10:18
The FA statement continued: "It is further alleged that the activity constitutes an "aggravated breach", which is defined in FA Rule E3(2), as it included reference, whether expressed or implied, to race and/or colour and/or ethnic origin.
"The midfielder has until 9 October 2019 to provide a response."Page 3: 10:20
FA guidelines state that a breach of rule E3 on social media would not immediately mean a six-match ban, as a proven offence on the pitch would.
Instead, a regulatory commission will decide what sanction it deems appropriate for the act committed.
Where the comments are "clearly pejorative and discriminatory", match-based sanctions can be imposed.
Mandatory education courses are also to form part of any sanction for a proven offence.
