Diego Costa 'El Diablo' Do we have a biter in Chelsea?

He got 2 yellows which make a red & was sent off but then a replay of the confrontation between Costa & Barry of Everton, showed that he bit or tried to bite Barry. He sunk or tried to sink his teeth, Dracula style, into Barry's neck. Even if it was only an attempt, it still constitutes a threat. In other words, I believe further sanctions await him. Diego always had the bad boy image but I believe it was compounded by Mourinho who indulged him & backed him every time he misbehaved. He is a great player & could be better still if he concentrated more on his skills than all the diving & fighting.
