David Moyes, the Everton manager, has been charged by the Football Association with improper conduct following comments he made about referee Mark Clattenburg in the wake of the derby defeat against Liverpool in October.

Clattenburg sent off Everton'sTony Hibbert and Phil Neville for conceding second-half penalties as Liverpool won 2-1 at Goodison Park.

But Moyes was incensed after his team were denied a late penalty when Jamie Carragher appeared to foul Joleon Lescott in the box, while Dirk Kuyt was only booked for a two-footed lunge at Neville.

Moyes has been charged comments he made immediately following the game and also in a press conference the following week.

"We deserved that penalty if not more and, if the other penalties were more blatant than that, then I am in the wrong game." Moyes said after the game.

"I am seemingly seeing football differently. If the referee does not see that you have got to ask why. Maybe they should not be there."

He added: "It can't just be me being bitter, people asked was the referee biased and I can't comment but we got nothing at all."

The FA said: "it is alleged that the comments made referring to referee Mark Clattenburg on each respective occasion amount to improper conduct as they call into question Mr Clattenburg's integrity and/or imply that Mr Clattenburg was motivated by bias."

Moyes has until December 11 to respond to the charge.

Sir Alex Ferguson also faces a charge of misconduct after clashing with Clattenburg at half time during Manchester United's game with Bolton Wanderers on Saturday.
