Footage has emerged of Chelsea fans chanting anti-Semitic songs on the Underground after the club's Premier League clash with Tottenham on Saturday.
In the video, fans of the Blues are seen and heard signing a degrading song on the District line following Chelsea's 2-1 win over the rivals at Stamford Bridge.
Clashes between the sides are often overshadowed by the behaviour of Blues fans towards Spurs supporters, who have a large Jewish fanbase.
Ahead of the match, Chelsea warned fans in the programme and on their website that the club will not tolerate similar instances.
