Diego Costa in in trouble with the FA after venting his frustration at referee Michael Oliver and possibly offending Everton supporters.
Chelsea striker Diego Costa has been charged with improper conduct over his behavior after being sent off in Saturday's FA Cup defeat to Everton.
Costa spent much of the 2-0 loss in a running battle with Gareth Barry, who was also dismissed at Goodison Park.
The Spain striker earned two yellow cards in squabbles with the former England man — the second following a confrontation that initially prompted suspicions Costa had bitten Barry.
