Joey Barton is due to appear before the French Football Association’s (FFA) ethical committee over a string of comments – including some of a transphobic nature – he made on Twitter about a rival player.
He also tweeted: “Secondly, Are you Pre-Op or Post-Op? #transsexual #thiagosaladyboy.”
Silva’s club, Paris Saint-Germain, said the comments were “unacceptable”, while Marseille apologised for the “inappropriate” posts.
Barton has over two million followers on Twitter.
Sky News reports Barton has been ordered to stop his personal attacks on the Brazilian international.
The two players were engaged in a vicious war of words.
Barton has been summoned to face the FFA committee today and could receive a ban over his comments.
He is at Marseille on a season-long loan from Premier League side QPR.
