Buck's call to fans

Chelsea's decision to replace the Portuguese coach with the 52-year-old Israeli has spawned a number of anti-Semitic comments which Buck says are unacceptable.

Buck declared: "We welcome all constructive points of view. 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."

Buck's latest revelations arrive as Chelsea's season showed no signs of improving. Their goalless draw against Fulham, Grant's first league game in charge of the Blues, was their fourth consecutive match without scoring.

But although they stretched their unbeaten home league record to 67 matches, Grant's problems were compounded with a serious injury to captain John Terry and a red card in the second half for returning striker Didier Drogba.

Terry saw a specialist and is to undergo an operation on a depressed fracture of the cheekbone after he was elbowed by Fulham's Clint Dempsey in the third minute.

Terry continued until half-time but was then substituted by Grant and the player's injury looks certain to keep him out for some considerable time.

He is unlikely to be fit in time for England's Euro 2008 qualifiers against Estonia and Russia despite suggestions from Chelsea staff that he will be able to return to training almost immediately.

Drogba will be suspended for one game following his dismissal for a second bookable offence but Buck is equally concerned with the reaction to Grant's arrival.
