Undercover footage taken for a BBC documentary reportedly shows supporters of Chelsea Football Club singing antisemitic songs, making gas chamber noises and performing Nazi salutes.
The incidents reportedly took place in France in October 2019 on the day that Chelsea beat Lille in the Champions League.
The group of fans were chanting: “We hate Tottenham – Yids! We hate Tottenham – Yids!”. Two members of the group appeared to be making Nazi salutes.
In another segment, a supporter is seen on a train leading a different song about the Tottenham player, Martin Chivers: “Chivers was a Jew. The thing between his eyes was twice the normal size. Yiddo, Yiddo, Yiddo.”
Also on a train in Lille on the same day, fans are heard in the video hissing, apparently to imitate the noise of a gas chamber.
The clips were filmed in the making of a documentary titled Shame In The Game, which explores the persistence of racism in football.
The Club pledged to investigate “as soon as we are able to view the video” after it is broadcasted tomorrow.
This is not the first incident implicating Chelsea fans in behaviour of this kind.
Last month, Chelsea unveiled a mural at its stadium to mark Holocaust Memorial Day.
