Co-chairmen David Sullivan and David Gold have urged West Ham supporters to avoid any unwanted behaviour when they start their Premier League campaign at home to fierce rivals Tottenham today.

With the club having come under scrutiny in the past — anti-semitic chanting and hisses have been heard, allegedly replicating gas chambers used during the Holocaust — the spotlight could again shift away from the on-field action.

But the chairmen, writing a message to fans on the club’s website, are keen to avoid any further incidents which would portray West Ham in a bad light.

A statement read: “West Ham United would like to thank all supporters who have purchased a ticket for Saturday’s season opening London derby with Tottenham Hotspur.

“The Hammers enjoyed three memorable wins against Spurs last season, with the resultant press coverage of each game rightly focusing on the action on the pitch, three outstanding performances from the team.

“Saturday’s game is likely to be an immensely passionate affair and, as ever, we know both sets of fans will be providing plenty of vocal support for their team.

“However, West Ham United seeks to remind all home fans attending the match at the Boleyn Ground that they will be acting as ambassadors for West Ham United.”
