Mancini tried to make light of suggestions he is now under even greater pressure to defend the Premier League crown.
He said: "I don't know this. You need to ask him (owner).
"I am happy with my job in two years here.
"I think that when you work and when you beat a team - sometimes you can have also a difficult moment.
"You can't win all the games and sometimes you can lose important games like in the Champions League, but this is normal for being on the top for a long time.
"Also Ferguson won his first trophy after seven years and his first Champions League after 14 years. I have another 12 years to win a Champions League!"
