Italian insists he will continue to be manager of English Premier League club next season.
Roberto Mancini upset by rumours over future at Manchester City
City have pointedly not rejected claims that have emerged from Spain that Manuel Pellegrini, the Malaga manager, will replace Mancini in the summer.
With a distant second-place finish in the English Premier League to Manchester United and yet another group stage exit in the Uefa Champions League, it is hard for Mancini to claim progress has been made this season.
And that was before Saturday's English FA Cup final defeat to Wigan Athletic who grabbed a last-minute victory thanks to Ben Watson's header.
It piles the pressure on Mancini, who concedes he cannot be sure of what his future holds because the club have not intervened on his behalf.
"If we find out in a week the things you say are not true, you have written a lot of stupid things in the last six months and more in the last two weeks," he said. "If it is true I am stupid because I didn't understand anything.
"You have been speaking about this for the last six months, and also the last two weeks. It is too much.
"The club didn't stop this. I don't think that was correct. I don't think it is true."
Mancini spoke at length with Khaldoon Al Mubarak, the club chairman, before the game, although he insists his future was not mentioned.
"I have a four-year contract, not one," he said. "There is no reason for me to ask. Do you think the chairman told me not to worry before the game?
"How many teams did better than us this year? Manchester United. Swansea, I don't think anyone else."
Mancini repeated his mantra that City's problems date back to the summer, when he is adamant they failed to move quickly enough in the transfer market, losing out on Robin van Persie in particular.
"Our target at the start of the season was to try and win the Premier League," he said. "But our mistake started in the last market. We didn't do enough to improve our team.
"After winning the Premier League, the second year is more difficult.
"Then maybe you don't get the Champions League. You can have a bad season. We had problems because we lost some players. We lost Yaya [Toure] for a month. We had a lot of problems this season.
"Every manager takes the responsibility. That is normal. But I don't think last year, when Manchester United lost the Premier League and didn't play in the FA Cup final they had all the discussion we did."
Yet Mancini accepted his team dropped well below their own high standards on Saturday, whilst at the same time claiming they deserved to win.
Most neutrals would say not, although Mancini had no complaints with the second yellow card for a challenge on man of the match Callum McManaman that condemned Pablo Zabaleta to become only the third player in FA Cup final history to be sent off.
"It was a correct yellow card," he said. "We were in a good moment, we were attacking, we lost the ball and they counter-attacked.
"In a final I thought we would be better but we had two incredible chances to score.
"We cannot do anything about it now but I am very sorry for my players and the club and for our supporters.
"There were 40,000 people here and we deserved to win this game."
