Tottenham Hotspur have come under renewed pressure to stop their supporters from using the Y-word as part of an attempt to fight against anti-Semitism.
The pressure has come from the government's advisor on anti-Semitism, Lord John Mann, and Chelsea chairman Bruce Buck.
"It impacts outside Spurs and, with a new stadium, I think they are in a position to tackle it far more effectively than they could in their old stadium. And I think they should be.
"There are things others can learn from Chelsea. Football can learn from it and you cannot underestimate how important this is."
Two years on from launching their anti-Semitism campaign, Chelsea became first sports club to adopt the International Holocaust Remembrance Alliance definition of anti-Semitism.
"From our perspective, after discussing it with the World Jewish Congress and other organisations, our view has been confirmed that the use of the word is inappropriate and that is what we tell our fans - the use of the word is inappropriate and don’t use it," Chelsea chairman Buck added.
"The fans get confused because they don’t understand why it’s inappropriate for them to use it as Chelsea fans, but it’s appropriate for Spurs fans to use it. And that makes it very difficult in our job to convince our fans not to use it.
"Having said that, I’m sure Spurs are aware of the issue and I’m sure they are considering how to deal with it as best they can."
Tottenham had a consultation over the use of the Y-word in December, with 94% of the 23,000 respondents acknowledging the Y-word can be considered a racist term, while almost half would prefer to see supporters chant the Y-word less or stop using it.
"We have always maintained that a reassessment of the use of the Y-word by Spurs fans can only take place effectively within an environment where there is also a zero-tolerance approach taken towards real anti-Semitic abuse," Tottenham said as part of their consultation.
"Sentiment around this term appears to be changing among the fanbase - there is a recognition of the offence the Y-word can cause and that a footballing context alone does not justify its continued use."
