CHELSEA have provided the English FA with a dossier of statements to support the allegation that referee Mark Clattenburg directed "inappropriate language" of a racial nature at John Obi Mikel, but dropped their complaint regarding Juan Mata due to insufficient evidence.
Players and officials have had a series of interviews with external legal counsel since their 3-2 league defeat by Manchester United and, with that process completed, Chelsea confirmed their complaint in relation to Mikel.
Signed witness statements -- from Mikel and Ramires among others -- were forwarded to the FA who, along with the Metropolitan Police, will now investigate the allegation. They will seek interviews with all relevant witnesses, including Mikel, Clattenburg and his team of officials, and will also request available video footage.
Clattenburg has made no public comment beyond welcoming the chance to establish the facts but is known to vehemently deny the allegation against him.
