Disciplinary proceedings have been opened against Chelsea over allegations of racist chanting at their Europa League match against Vidi in December.
Uefa announced the news on Tuesday morning, based on "the report submitted by the Uefa Ethics and Disciplinary Inspector commissioned to conduct an investigation".
During the game with Vidi in Hungary it was alleged a number of Chelsea fans sung a derogatory song about Tottenham featuring anti-Semitic language.
Chelsea chairman Bruce Buck condemned the actions of "a few mindless individuals at some of our recent matches" and added the club "will not rest until we have eliminated all forms of discrimination from our club".
Chelsea launched a campaign in January 2018 to raise awareness and educate about anti-Semitism in football.
The Blues have been drawn against Malmo in the next stage of the Europa League, with the two-legged tie to be played on February 14 and February 21.
