Mancini and his players are still reeling from Sunday's dramatic derby defeat at home to United and now trail their rivals by six points in the Barclays Premier League.
However, Mancini told a function in Italy that he still believes his team to be better than that from the red half of town.
"United have more experience but we have a much better team and play much better football," the Daily Mail quoted Mancini, as saying.
According to the paper, Mancini's relationship with young striker Balotelli is also under the microscope again this week after he substituted the 22-year-old after 50 minutes on Sunday.
However, it seems, though, that Mancini is prepared to keep faith in the enigmatic forward.
He added: "We are waiting for the moment he becomes aware of his talent. That is why he is not for sale." (ANI )
