Although there is still one game remaining this weekend, the midweek tie between City and Spurs has been billed as a Champions League decider.
A win for the Citizens would put them in the driving seat and if they manage to qualify for the competition next term then there appear no bounds to the prosperous club’s potential, with many star-studded names likely to arrive in the summer.
Mancini, who has been at the club for five months, cannot wait for the Tottenham clash.
"I know this is an important moment for the club," said the Italian, according to the Manchester Evening News.
"We have worked for this. All the players have worked for this target.
"I have worked here for five months. I can build a good future here. We are trying to change the history of the club."
Mancini has been under pressure from the start of his reign, as it was clear that predecessor Mark Hughes was sacked because the ownership were not confident that he would deliver their top-four quest.
However, the former Inter coach insists he will be at the club next season, whatever the outcome of the final two games.
"My future does not come down to this game," he added.
"We have qualified for the Europa League next year - that is important. Now we have a chance to do more.
"Tottenham are a good team. They have very good players and a good manager, who is very experienced.
"They have been fantastic in the Premier League this year. Now Tottenham and ourselves must play for fourth position. It is fantastic for us and them.
"I can see how much people here want this. I would like all the people who work here and come tomorrow to leave with a good feeling.
"I like this situation."
