Tottenham Hotspur and Chelsea have warned their supporters to behave throughout Tuesday’s League Cup semi-ultimate leg at Wembley immediately after the latest incidents of discriminatory behaviour.

Blues supporters have been underneath the spotlight in the latest weeks immediately after a number of significant-profile incidents, like a derogatory chant about Spurs supporters that highlighted alleged anti-Semitic language at a Europa League match in Hungary last month.

“This fixture is always a passionate face both of those on the pitch and in the stands, but in light of the latest gatherings and immediately after consultation involving both of those clubs and the Metropolitan Police, we would like to remind supporters of their responsibilities in trying to keep support optimistic,” Chelsea reported to fans in a statement.

“Historically, a smaller minority has employed the Tottenham fixture as licence to use anti-Semitic chants, noises and gestures…. Our position is distinct — this is no excuse for abusive chanting or behaviour and it will not be tolerated.”

In the meantime a Spurs enthusiast was banned and fined for throwing a banana skin at Arsenal’s Pierre-Emerick Aubameyang throughout the North London derby in early December.

A statement on Tottenham’s web-site reminded ticket holders that “foul, abusive, homophobic or racist behaviour will not be tolerated”.
