Diego Costa reported for alleged assault on Stoke City steward (Pic)

Chelsea's nightmare start to the season may be about to get a whole lot worse.

On top of losing 1-0 to Stoke, the defending champions may have to do without star striker Diego Costa after the Brazilian-born forward was reported to referee Anthony Taylor for allegedly assaulting a steward. https://twitter.com/sammatterface/status/663084727654612992 Chelsea have enough problems as it is without dealing with something like this. Costa makes contact with the steward when attempting to retrieve the ball, but in fairness to the Spanish international, there doesn't seem to be a whole lot in it.
