The 25-year-old underwent a medical on Friday evening and signed a deal to become City's fifth capture of a busy transfer deadline day. Maicon, Scott Sinclair, Richard Wright and Matija Nastasic had joined the Barclays Premier League champions earlier in the day.
City gave no details of the length of contract while reports claimed the player was likely to have cost around £16million.
The former Real Madrid player will effectively replace Nigel de Jong in the squad after the Holland international left for AC Milan.
The deal was completed just before the 11pm transfer deadline and confirmed afterwards.
