Chelsea fans have damaged the club's reputation after being filmed singing anti-semitic songs about Tottenham on Saturday.
The rivalry between the two clubs has intensified over the last few years thanks to several fiery encounters including the 2-2 draw at Stamford Bridge last season, which ended Tottenham's Premier League title hopes, and Chelsea again got the better of their London rivals on Saturday, this time in the FA Cup.
Goals from Willian, Eden Hazard and Nemanja Matic helped Antonio Conte's side record a 4-2 win over Mauricio Pochettino's team, who responded through Harry Kane and Dele Alli, but that victory has sadly been tainted after footage emerged of a group of Chelsea fans singing anti-Semitic songs.
The Sun says supporters of the Stamford Bridge were gathered at a pub before the semi-final, singing: " We’ll be running around Tottenham with our w*llies hanging out, singing I’ve got a foreskin haven’t you."
The club has previously courted controversy for racist behaviour, with supposed Chelsea fans stopping a black man boarding a train in Paris in 2015, while captain John Terry was previously found guilty of racist conduct against Anton Ferdinand, being banned for four domestic games and fined £220,000.
Tottenham, like many clubs in London, have a large Jewish following and thus the songs sung take on an anti-Semitic tone. Charities Action against Discrimination and the Board of Deputies of British Jews say they will try to catch those responsible along with police.
A spokesperson said: “AAD, together with the BOD have called on Chelsea FC and Tottenham Hotspur FC, the FA and Metropolitan Police to come together and take a stand against racist singing and chanting ahead of this weekend’s FA Cup semi-final between the two clubs.”
