West Ham who have been struggling with a lack of defenders due to injury are said to be interested in taking Micah Richards and Matija Nastasic to the Boleyn Ground.
The Hammers would struggle to match City's asking fee for the duo so are said to be putting together an offer to take them both on loan.
Serbian international Nastasic is also wanted by Juventus and Roma.
Nastasić signed a five-year contract with City, ending on 30 June 2017. He was part of an exchange deal with Stefan Savić. While Richards joined City as a 14 year old making his debut against Arsenal in 2005.
