The message addressed to Grant said the powder was lethal and included the words: "You are a back-stabbing Jewish b******. When you open this letter you will die a very slow and painful death."

It has been said that death threats of a sexual nature have been sent to Grant's wife, Tzofit, who is a TV personality in the couple's native country of Israel.

A Surrey Police spokesman said: "We were called to Chelsea's training ground at Cobham at 12.15pm (on Tuesday) after they received a suspicious package.

"A white powder contained within the package was analysed by specialists from Surrey Fire Service and was determined to be a harmless substance. Detectives are continuing investigations to identify the source of the package."

But the idiots who sent the pckage didn´t seem to realise that Grant and Chelsea were in Athens prior to their their Champions League draw with Olympiacos.  Chelsea have refused to comment any further on the matter.
