Union: Chelsea owe Clattenburg apology

The referees' union Prospect has stepped up calls for Chelsea to apologise to Mark Clattenburg and claimed the club made a number of errors of judgment in their complaint.

Prospect national secretary Alan Leighton said the union did not intend to take legal action against Chelsea, but that the London club should feel morally obliged to make amends via an apology and compensation.

Clattenburg has been cleared by the FA of the accusation that he said "shut up you monkey" to Nigerian midfielder John Obi Mikel during Chelsea's 3-2 defeat by Manchester United on October 28, and Leighton said: "Chelsea have done a number of things wrong with this case."
