The Chelsea chairman, Bruce Buck, has attacked an element of the club’s support for anti-semitic abuse of the new manager, Avram Grant.

The Israeli’s appointment as replacement for Jose Mourinho has provoked criticism among the club’s support, but Buck believes that some of the comments have been unacceptable.

“We welcome all constructive points of view,” Buck wrote in Saturday’s match programme for the visit of Fulham. “But there have been a few which could be viewed as racist and anti-semitic and that must stop immediately.

“This is one thing we will not tolerate whether in written correspondence, on the chat pages, on posters or banners or through singing and chanting. And it unfairly smears the reputation of the vast majority of Chelsea fans who rightly do not want to be associated with such activity.”

Chelsea supporters were heard chanting the name of Mourinho during the second half of their goalless draw with Fulham at Stamford Bridge.

The club’s billionaire owner Roman Abramovich, who sat with fans in the Shed stand instead of his private box, was forced to suffer the chants.
