Mancini has openly admitted that he will wield the axe for the FA Cup tie at home to Leeds United this weekend but wants his squad as a whole to produce a positive finish in all competitions.
He told reporters: "We now have 12 games left, we need to do well in the Premier League and the FA Cup.
"We can do better. We need to finish the season the way we did last season.
"Every team that plays against us plays like it's the Champions League final, this is normal."
City's next Premier League match is at home to Chelsea on Sunday, February 24.
