Chelsea have vowed to ban any supporters found to have used antisemitic language or behaviour 'which shames our club' during Monday's Premier League match at Watford.
A report on jewishwebsite.com claims Chelsea supporter Jonathan Metliss was left 'disgusted' with the chanting he heard from fellow Blues fans at Vicarage Road.
According to the article, Metliss, who is the chairman of the Action Against Discrimination charity, took pictures of the alleged perpetrators and reported the incident to nearby stewards before being moved to the family enclosure 'for his own safety'.
Chelsea last week launched a 'Say No to Antisemitism' campaign as part of their own inclusion work through the Building Bridges initiative.
