The two assistant referees and fourth official on duty in Sunday's controversial Chelsea-Manchester United clash look set to give their full support to referee Mark Clattenburg in the Football Association's forthcoming investigation, Press Association Sport understands.
Chelsea lodged a formal complaint with the FA on Wednesday night over the "inappropriate language" they claim Clattenburg used against John Obi Mikel in their 3-2 defeat at Stamford Bridge last weekend. The club have submitted a dossier of evidence which contains accounts given by the players, who allege the 37-year-old official used a term which has been interpreted as racist.
Clattenburg denies the allegation and it is understood that assistant referees Michael McDonough and Simon Long and fourth official Michael Jones also believe he is innocent.
