Eden Hazard led calls for restraint by Chelsea and Tottenham fans in Tuesday night’s League Cup semi-final, a match for which Scotland Yard will stage its biggest match-day security operation in recent years to combat a spike in anti-Semitism.

A “zero-tolerance” plan on hateful language has been devised by the Met Police, Spurs and Chelsea after recent warnings failed to combat a series of hateful incidents. Chelsea already face potential Uefa sanctions over anti-Jewish chanting and are now desperate to avoid further embarrassment. Club owner Roman Abramovich, who is Jewish, launched a clampdown on anti-Semitism only last year.

On Monday night, Hazard, the club’s biggest star, launched an impassioned plea for calm. “I want people to remember the game for the right reasons,” he said. “I just want all the fans to watch and enjoy the match. One team will win, one will lose, but try to act with fair play.”

Chelsea have been liaising with Tottenham and Scotland Yard since the semi-final draw was made last month to formulate a plan which includes:

At least 100 extra uniformed ­officers inside Wembley and around train stations.

Uniformed police spotters will listen for hateful language.

Social-media efforts by police ­before kick-off to remind fans that “hate crime will not be tolerated”.

Chelsea stewards to attend with the power to eject any of the 5,000 visiting fans.

A message in the programme urging fans to report abuse.

Security and policing provided by Tottenham and Wembley was already due to be higher than usual as it is a category A fixture. Tottenham could face a bill of around £20,000 from the Met for the ­increased support.
