Tottenham have condemned a section of their supporters for alleged homophobic chanting during Wednesday's Carabao Cup semi-final first leg defeat at Chelsea.
Spurs said they "urge supporters not to use" a particular chant in future.
"No-one should suffer discrimination because of their sexual orientation and/or their gender identity," Spurs said.
Proud Lilywhites, the club's LGBTQ+ supporters' association, said people should "think before you chant".
The fans' group went on to say the chant in question "has been used to victimise young gay men for years".
"We know most fans don't sing this with any intent to discriminate, ostracise or demean us but the impact it has shouldn't be underestimated," the group posted on Twitter.
