Manchester City midfielder Rodri has been charged with misconduct by the Football Association following comments he made about referees after his side's 2-2 draw at Tottenham earlier this month.
The 29-year-old was left frustrated by a Dominic Solanke goal being allowed to stand after the Spurs forward appeared to kick through the leg of the Manchester City defender Marc Guehi.
While the FA did not specify the exact comments the charge relates to, Rodri accused referee Robert Jones of not being "neutral" against City.
"I know we won too much and the people don't want us to win, but the referee has to be neutral," said the Spain international after the game.
"It's not fair because we work so hard. When everything is finished, you are frustrated."
Rodri is accused of acting in an "improper manner" by making comments that "imply bias and/or question the integrity of a match official".
He has until 18 February to respond to the charge.
In his post-match comments, Rodri also alleged City had regularly fallen victim to poor decisions by officials in this campaign, where they are currently second in the Premier League table, four points behind Arsenal.
"It's one game and another game and another game - and it's not possible," he added.
"Honestly, I never speak about referees, I respect their job massively. But they have to pay attention to these things.
"He (Solanke) kicked the leg, it's so clear... It's two, three games in a row and I don't know why."
