City boss Roberto Mancini has reportedly named the Russian star as one of his main targets for the summer transfer market.
Izmailov’s agent Paulo Barbosa told News of the World: “City want to sign Marat and have done for a long time.
“He’d be interested but the problem is the price. Sporting want £20m, but City are refusing to pay that.
“City have said they will only pay £10m, but a compromise could be reached.
“He made his debut for Russia when he was just 19 and is one of the best players in Portugal, so you can see why they want him.”
