Mancini praised Joe Hart, whose form has been questioned in recent weeks and criticism increased after his display in England's midweek friendly loss in Sweden.
Mancini said: "This is his job.
"He received criticism from you (press) after the international game, but this is part of our life.
"Sometimes you can do well, sometimes you can do bad games.
"But it is important to have very strong characters in this situation. Today he saved in the first half (in) an important situation."
