The 22-year-old only joined City from Hamburg last summer but failed to secure a regular first-team place at Eastlands and made most of his appearances out of position at full-back.
With next year's European Championship on the horizon Boateng is keen to play more regularly at centre back to secure his place in the German national team and so jumped at the chance to move back to the Bundesliga.
However, the move depends on City agreeing a deal with Bayern, something Boateng is desperate for them to do.
"It is true that I have agreed with Bayern on a four-year deal. Now it is up to Manchester to make it work. At the moment they are making things a bit difficult," Boateng told Kicker Magazine.
"It is about the position. Bayern want me as a central defender. That is also an advantage for the national team.
"My dream is to have a starting spot within a year, hopefully at Bayern, and then I want to win the European Championship."
Bayern Munich captain Phillip Lahm has welcomed the proposed deal and confirmed it is now up to City to ensure the move goes ahead.
"Things are not up to Jerome or Bayern Munich, Manchester City will have to agree in the end. At this point in time I do not know what might happen," he told Bild.
"I am unable to make a prediction on this, we simply have to wait and see."
