Manchester City boss Mark Hughes has been asked by the Football Association to explain the comments he made after Craig Bellamy's dismissal in the Premier League draw at Bolton on Saturday.
Bellamy collected two yellow cards in the second half of the 3-3 draw, the first for dissent and the second for a supposed dive, although replays suggested the City striker was fouled.
Hughes later claimed that referee Mark Clattenburg had joked that he did not like the Welshman at half-time.
"I don't appreciate when the referees coming out for the second half start making comment about who they do or do not like in my team,'' Hughes said.
"They might be having a laugh and a joke. I have to be careful here as we are talking about integrity.''
Hughes has taken the stance that now the FA are involved, his best course of action is to keep his counsel on the matter. However, he was clearly unhappy on Saturday and his view has not changed.
"I said what I said on Saturday is still on record and I stand by it,'' he said. "The FA have asked for my version of events so I can't really discuss the matter any further.''
Hughes has until December 22 to respond to the FA, while Bellamy will miss tomorrow's encounter with Tottenham as he serves his one-match ban.
