Mancini blew a fuse after being pressed on his claims of talks with AS Monaco.
Mancini, who banged the table with his hand, said: "You need to have respect for the people sometimes. I don't understand why you continue to ask me this. Why?
"You asked me one question. I am polite because I answered your questions.
"I didn't answer because I was there to talk about West Ham. I am polite because I answered, I said it is true - every year I can have two or three new situations where I can go (but) I want to stay here.
"I decided to stay here because I worked for two-and-a-half years, I worked hard. The future will be easy because when you have a new team the strong work is the first few years when you need to build your team.
"But we won three trophies in two years. I think you should have respect for this, for me, for the club, for the players. I don't understand why every time we talk about this."
