Manchester City head coach Roberto Mancini wants to see an end to some of his players complaining to the press about a lack of opportunities at Eastlands.
The likes of Shay Given, Emmanuel Adebayor and Craig Bellamy have all been outspoken about their City prospects, with Bellamy subsequently moving to Cardiff City on a season-long loan.
That situation has annoyed Mancini, who said: "I played football. Sometimes I had this behaviour. I can understand it, so it is not frustrating for me.
"But at the same time it is important they start to change their mentality. If they want to become a top squad and a top team they must change it.
"It is impossible that every three days players do interviews complaining that they are not playing.
"They need to knock on my door and speak with me so I can explain the situation.
"I want to create an atmosphere like they have at Chelsea and Manchester United, but maybe it is easier for them to accept it because they have had success."
