LONDON (Reuters) - Chelsea striker Diego Costa has avoided disciplinary action after appearing to kick out at Liverpool's Martin Skrtel in Saturday's 3-1 defeat, according to English Football Association sources.
Referee Mark Clattenburg is understood to have seen the incident and opted against issuing a caution, meaning there can be no retrospective sanction by the authorities.
