Chelsea fans have been accused of racist chanting in their Europa League draw away at Vidi on Thursday night.
UEFA has been made aware of alleged racist chanting at the Groupama Arena in Budapest where Chelsea fans were reportedly heard using an anti-Semitic term in a song aimed at rivals Tottenham.
This follows a club and police investigation into alleged racist abuse aimed at Raheem Sterling at Stamford Bridge last weekend.
UEFA will wait for reports from match officials and its match delegate before deciding whether or not to take the matter further. Charges against clubs are usually filed within 24 hours.
A Chelsea spokesman said: “Anti-Semitism 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 anti-Semitic or racist words or actions will face the strongest possible action from the club.”
The Jewish Leadership Council described the incident as “thoroughly depressing”, but endorsed the club’s condemnation of the chants.
JLC chief executive Simon Johnson said: “We utterly condemn this second incident of racism by Chelsea fans in a week.
“The latest anti-Semitic incident is thoroughly depressing, especially in light of the dedicated work that Chelsea FC has done to address the problem.
“We completely endorse the club’s strong statement and would support them in any robust action which they now take against the perpetrators.”
Chelsea in January launched a campaign to raise awareness and educate people about anti-Semitism in football.
In October, as part of the ‘Say No To Antisemitism’ initiative, the club were reportedly considering a proposal to take racist fans to Auschwitz to re-educate them. Chelsea have already organised and paid for two 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 anti-Semitic abuse football.
