The FA has charged Diego Costa with misconduct after the Chelsea striker was sent off last Saturday in the FA Cup clash at Goodison Park.
Costa, who has until Thursday to respond to the charge, was sent off after an angry reaction to a tackle from Everton’s Gareth Barry just after Lukaku’s second goal, in the end of the game.
Replays appeared to show the Blues forward opening his mouth towards Barry’s neck while the pair were tangled together, but Barry later said he was not bitten.
“It is alleged his behaviour, after being shown a second yellow card in the game, amounted to improper conduct,” the FA statement read.
The FA also stated that Costa has until Wednesday to explain a gesture directed to Everton fans at half-time.
