Chelsea fans have been accused of racist chanting in their Europa League draw away at Vidi

The Union of European Football Association (UEFA) was made aware of alleged racist chanting at the Groupama Arena in Budapest where Chelsea fans were said to have been using an antisemitic term in a song aimed at rivals Tottenham.

Charges against clubs are usually filed within 24 hours and UEFA has decided to wait for reports from match and delegates before deciding whether or not to take the matter further.

A Chelsea spokesman said: "Antisemitism and any other kind of race-related or religious hatred is abhorrent to this club and the overwhelming majority of our fans. It has no place at Chelsea or in any of our communities. We have stated this loud and clear on many occasions from the owner, the board, coaches and players.

"Any individuals that can't summon the brainpower to comprehend this simple message and are found to have shamed the club by using antisemitic or racist words or actions will face the strongest possible action from the club."

In January, Chelsea launched a campaign to actually raise awareness and educate people about antisemitism in football.

Also, in October, as part of the Say No To Antisemitism initiative, the club reportedly considered taking racist fans to  Auschwitz in a bid to re-educate them. They succeeded in organizing and paying for two of those trips to Auschwitz this year for club executives, staff and supporters. Just last week, inclusion campaign Kick It Out released a short film produced with the support of Chelsea, aiming to tackle antisemitic abuse football. So there is a lot to wonder why they would fall back on using antisemitic terms.
