Roberto Mancini's assistant says that those who have recently criticised the club have not witnessed the 'camaraderie' amongst the squad on matchdays or on the training pitch
The Premier League champions have had a series of widely-reported off-field distractions this season, such as Carlos Tevez's self-imposed exile and the antics of Mario Balotelli.
But Kidd believes that it is about time that the media stopped focusing on such matters, insisting that he has faith in his players.
"I have got great belief and great trust in this squad. And I couldn't believe it when the critics came out about the spirit and camaraderie or whatever,” he told the Daily Star Sunday.

"Unless you are working every minute of every day with these players then you can't give an opinion.”
The former Manchester United No.2 also underlined the team spirit at the club, as highlighted by their title victory this season.
"People have been constantly taking cheap shots at us," he fumed.
"The people who question the spirit here are outsiders. They just don't know. If you see them supporting one another on matchdays and in training, nobody would be questioning the camaraderie.
"But if there was any doubt you only had to see it against QPR [the 3-2 win to clinch the title] to answer that."

"Some people, too, are unhappy about the money that's been spent. But I'm sad to say that modern football is about money," he added.
