Manchester City assistant boss David Platt believes the negative reaction to his side's second goalless draw in four days is a sign of the high expectations expected of the club.
The Blues were booed off following Saturday's stalemate with a Birmingham side who are now anchored in the bottom three.
"It is a compliment to where this football club has come to," countered Platt.
"There is huge frustration amongst the supporters but that exists within the players and management staff as well.
"If we don't win a game at home that we expect to that is what will happen.
"But part of that is down to the objectives we are trying to meet, which in itself shows how far this football club has gone in the last couple of years."
Certainly there is an element of mistrust about Mancini's apparent defensive tactics.
"People think Yaya Toure is a defensive midfield player. But he spends the majority of his time in the opposition half," he said.
"Nigel de Jong sits, quite rightly, because tactically you have to be balanced.
