"Every word I say is a big risk for me," said the Chelsea boss, who was speaking at Waterstones Piccadilly to promote his book "Mourinho."
"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 word 'afraid' is a punishment, and a hard punishment. But to say the referee was 'weak and naive', referring to one of the top referees, not just in this country, also in Europe, to call him 'weak and naive' we can do.
"The only good thing of this last decision by the FA is that every manager in this country can write in a little book and, when he goes to the press conference, he knows that 'afraid' costs £50,000. 'Weak and naive', you can do it.
"It's more important for the football in this country -- a word, than [an] aggression. The only two good things that I take from this (the FA decision) is that. It's good for everyone.
"And it's the fact I still can walk in London without an electronic tag."
"If you ask me how many years I'm still going to coach, I'd risk 15 more," the 52-year-old said. "I'm in the middle: I did 15, I have 15 more to do. I'll finish at 67. Maybe later if I can. Can I stay 15 more years at Chelsea Football Club? I don't think so.
"I don't think modern football allows it any more, so normally I will not finish my career at Chelsea. I would like to, but I don't think it's possible."
The book is a pictorial story of Mourinho's management career to date and celebrates his achievements.
"The fact that the book comes in a moment when my football results are contradictory to the history I have in this book is just a detail," Mourinho said. "I don't need the book to know what I did. The people who like me don't need the book to know what I did.
"The ones who don't like me are enjoying the moment now, and obviously they are not going to buy the book and spend some time looking at it."
Further speculation of a player mutiny emerged on Thursday and Mourinho made light of the rumours. He listed those who had spoken out in support of him and then racked his brains for those who had not, joking they would not face Villa.
He said: "I think the mutiny must be... Baba [Rahman]. Baba... who else? Falcao? Papy Djilobodji? Oscar? So these four don't play Saturday for sure."
He also said he would not write a controversial book, insisting differences should remain within the team environment.
"There are things in football that are to stay forever in the clubs, in the squads, in the dressing rooms, in every match," Mourinho said. "And I don't see myself writing a controversial book, ever."
In a separate interview with talkSPORT, Mourinho spoke about claims he has issues controlling Chelsea's dressing room.
He said: "It's sad but I don't care really, I don't care. I spoke with the players about it and the players are also sad about it, but there is no way to care."
