City's 1-1 draw at home to the Spanish giants confirmed their failure to reach the last 16, a development which shocked the Portuguese and prompted him to comment about the Italian's position.
But Mancini told reporters: "Mourinho is not my chairman, he is not my owner. What Mourinho said is for me not interesting. Mourinho wants to talk about everything. For me, it is not important."
When asked if the comments came from the Madrid coach's jealousy of his position, the Italian suggested: "Sometimes it could be. But I will not stay here 20 years. In this moment I am here and we are working well."

"They know it is impossible to win every game," he remarked. "When we lose, they are disappointed, like me or the players. We can't be happy; we went out of the Champions League.
"All I can say is I am happy to work with my owners and chairman. They are good men, they understand.
"But we are not Real Madrid, Manchester United or Bayern Munich, who used to win every year for 100 years. We are Manchester City. For 35 years we didn't win; in two years, we won three trophies."
