Chelsea and West Brom have been charged by the Football Association because of the conduct of their players in a 2-2 draw on Wednesday.

The charge relates to the reaction of players when Baggies midfielder Claudio Yacob escaped a second yellow card for a foul on Diego Costa.

The clubs were deemed to have failed "to ensure their players conducted themselves in an orderly fashion".

They have until 18:00 GMT on 20 January to respond.

Chelsea interim boss Guus Hiddink believed Yacob should have been dismissed and spoke with fourth official Jon Moss during the game.

"I told him: 'This is one of the worst referees of the Premier League I have experienced,"' said Hiddink, speaking on Friday before Saturday's match against Everton.

"He said to me 'you haven't seen me yet', which was a beautiful remark I think."
