Referee Mark Clattenburg is apparently "angry and confused" after Chelsea's allegations he directed "inappropriatel language" towards two of their players in Sunday's controversial 3-2 defeat to Manchester United at Stamford Bridge, according to former official Graham Poll.
• Clattenburg affair is a crisis
• Chelsea lodge official complaint
Speaking on talkSPORT, Poll revealed the feelings of his former colleague and said he is set to protest his innocence.
"I know he's feeling angry because he doesn't feel he's done anything wrong - he's angry and confused.
"He's angry because he's being accused of something he doesn't feel he did, and confused because, in his mind, he's done nothing wrong and yet ended up as the victim.
"That's the bit you look at and go 'why?' You think, 'what's going on?' And there's this media circus."
It emerged on Wednesday, however, that Chelsea are set to make a formal complaint to the Football Association over Clattenburg, but have dropped one of the claims regarding one player.
