Roberto Mancini is calling on Blues fans to be the team's 12th man in Sunday's vital Barclays Premier League six-pointer against Liverpool at the City of Manchester Stadium.
City players have told the Blues boss about the special atmosphere that lifted last season's UEFA Cup quarter-final thriller with Hamburg and "Bobby Manc" wants to enjoy it for himself.
Champions League regulars Liverpool and their 3,000 fans will arrive at the Stadium in fifth place and just a point adrift of the fourth-placed Blues, who also have a game in hand.
Mancini said: "This is a huge game and everybody can play their part, the fans as well as the players. I have been very impressed by our supporters since I have been here.
"It is so important to the team and I know just how much they appreciate it. They are the 12th man, and the louder they are on Sunday the better against one of our closest rivals."
City players too are particularly keen to savour the colours, scarves and flags while "Blue Moon" raises the roof to drown out traditional Liverpool anthem "You'll Never Walk Alone".
Midfielder Nigel de Jong said: "I love the City fans and the fighting spirit they have – it’s something I can really relate to. And they know this is a match that we have to win.
“I see the passion our fans have for this club - they have City in their hearts and they'll give their all to support the team in every aspect they are involved."

We'll need more than a 12th man if we play the way we have been against Liverpool.
