Chelsea manager Jose Mourinho will appeal against the Football Association's £50,000 ($77,200) fine and one-match suspended stadium ban, saying: "I have to be honest with myself."
Mourinho was sanctioned for comments made following the October 3 loss to Southampton in which he said referee Robert Madeley was "afraid" to give the Blues a penalty.

The Portuguese on Friday confirmed he had received the FA's written reasons and will appeal.
"I have to be honest with myself. It's the most important thing so I have to appeal," Mourinho said.
"The moment we got the written reasons and I decided to appeal is the moment to stop with my opinions and not to add anything more than I did already.
"I think I was very objective in my sadness facing the situation."
Mourinho on Thursday night addressed the sanction, which was announced by the FA on Wednesday.
"Every word I say is a big risk for me," he said on Thursday.
"I am happy that I don't have an electronic tag. I think it's not far from (that).
"I also think that £50,000 in the world where we live today is an absolute disgrace.
"And I also think that the possibility of getting a stadium ban is also something absolutely astonishing."
The stadium ban will be imposed if Mourinho speaks out of turn in the next 12 months, but it is understood the FA is unlikely to pursue Thursday night's comments.
