Diego Costa: Chelsea striker is accused of assault at Stoke
Chelsea striker Diego Costa has been accused of assault by a Stoke City steward following Saturday's game.
A complaint was made to match officials after the Spain international, 27, is alleged to have made contact with the steward's foot while retrieving the ball for a throw-in.
A Chelsea spokesman said the claims were "utter nonsense".
The Premier League champions were beaten 1-0 at the Britannia Stadium, Marko Arnautovic scoring the winner.
