Spartak Moscow have become embroiled in a fresh racism row after posting a tweet about three black players.
The update, which was posted on Saturday morning and featured the players practising during a training session, read: "See how the chocolates melt in the sun".
The post, featuring chocolate bar and sun emoji symbols, has since been deleted.
The incident comes just six months before Russia hosts the World Cup, and is the second alleged incidence of racism in which the club have been involved this season.
Liverpool complained to UEFA last week after Reds striker Rhian Brewster was allegedly the subject of racist abuse from Moscow players in an Under-19s match in December.
Spartak fans were also found guilty of racial abuse against Liverpool youngster Bobby Adekanye in the UEFA Youth League in November.
