The Manchester City boss is having to deal with weekly stories about disenchantment in the camp, with Shay Given and Emmanuel Adebayor the latest players reported to be unhappy.
However, Mancini is all too aware that, with so many big names in his squad, it is going to be impossible to please everybody.
"It is impossible that all the players are happy," he said.
"At every club it is normal, 11 players are happy, the rest are not.
"If a player is happy when he does not play, he is crazy. It is important that he is unhappy.
"It is also important that he continues to work so that I have a chance to change my mind."
