West Ham United are chasing Manchester City defensive pair Micah Richards and Matija Nastasic.
The London Evening Standard says City have made both players available for transfer and the Hammers, who currently have only one fit centre-half in Winston Reid available for Saturday's London derby at Crystal Palace, could be interested.
West Ham would favour loan deals, with Serbia international Nastasic valued at around £12million and City looking for at least £7m for Richards.
Italian clubs Juventus and Roma are thought to be interested in Nastasic, who joined City from Fiorentina in 2012 but has struggled for a regular run in the first team.
