The BBC are among numerous outlets reporting that the 23-year-old is set to sign with an official announcement expected next week.
Some reports suggest that Mangala has already completed his medical and will join up for pre-season after a post-World Cup holiday.
Mangala was part of Didier Deschamps' World Cup squad but did not make an appearance. He has three international caps.
With Joleon Lescott having left City for West Brom in the summer, they have been looking for a centre-half, and Mangala appears to have been identified as Vincent Kompany's long term partner at the centre of their defence.
