There is growing unease that the manager has tried to rewrite history by claiming that signings like Jack Rodwell, Javi Garcia, Maicon, Matija Nastasic and Scott Sinclair were made by the club after they failed to land his top targets.
A City source told the Sunday Mirror that every aspect of last summer's recruitment drive was endorsed first by Mancini.
But his future will also be shaped by the future as well as the past. With the club investing in a new Academy, directors Ferran Soriano and Txiki Begiristain have been told to develop a model similar to the one they put in place at Barcelona.
That gives them authority to decide on how City will play from junior level up to the first team.
And while Mancini is less than 12 months into his five-year contract, he is yet to show any kind of willingness to bend towards the will of the two Spaniards.
