Chelsea were pleading with their fans yesterday to keep the atmosphere at Wembley “positive” with worries that there could be anti-semitic chanting at the League Cup final.

With Tottenham’s links to London’s Jewish community and Blues fans in the past chanting anti-semitic songs — something the club have admitted — the Blues are reminding fans of the responsibility they have to the club.

Anti-semitic chants were filmed after Spurs’ 2-2 draw with West Ham last weekend and Chelsea are keen to avoid a repeat with their fans, threatening severe action to anyone caught taking part in discriminatory chanting.
