Mancini could come under huge pressure if City are beaten by Manchester United today.
A source close to Mancini told the Mail on Sunday: "Roberto cannot say for sure that he will be at City next season because it doesn't depend on him.
"But if he is sacked, City's owners are going to have to pay him an awful lot of money. He will still have four years left on his deal at £5.5million a year. That's £22m it will cost to get rid of him."
