Roberto Mancini has grown frustrated by the City’s lack of transfer activity at the Etihad Stadium and is now prepared to make his first foray into the market.
An anchor man to provide competition for Gareth Barry and Nigel De Jong is high on his wanted list Italy international De Rossi emerging as a serious target following his displays at Euro 2012.
Stadio Olimpico sporting director Gabriele Sabatini has warned the Premier League champions that they will have to table a ‘monstrous bid’ in order to land the 29-year-old.
“I never said De Rossi is not unsellable. I just made a general consideration regarding the whole of football.
“If a monstrous bid materialised we would evaluate it, but we are not looking for buyers for Daniele because he is a pillar of our team.
“For us he is a player of extraordinary importance and not replaceable, so it would be too difficult to do a deal even if there was an indecent proposal.
“We have not set a price for De Rossi. Fiorentina ask €30million (£23.5m) for (Stefan) Jovetic? The figure for Daniele is higher than that.”
Denmark star Agger is also a major target for Mancini and wants him to partner captain Vincent Kompany at the heart of the City defence as they prepare for their first ever title defence.
Reds chief Brendan Rodgers underlined the brutal reality of life by conceding that he could be prepared to cash in on the 27-year-old to fund more signings.
“Thiago Silva has left AC Milan for PSG for £40million.
“He (Agger) is one of the leading players in European football, so it is going to be a big valuation.
“Is he a player I want to lose? No. He understands how I want to work and can play a real pivotal part in how I want to play.
“But I am a realist. If someone comes in with a massive bid and it is in the best interests of the club, whether it is Daniel or any other player, you have to look at it.”
