Sochaux have officially completed the signing of Florentin Pogba in a deal that runs until 2023.
An announcement by the Ligue 2 club of his capture was made last week subject to a medical.
Pogba joins having been a free agent since his contract with MLS side Atlanta United expired.
It makes it the third time the senior brother of Paul Pogba plies his trade in France having previously featured for Sedan and Saint-Etienne.
The 29-year old Guinean famously came up against his brother during a round of 32 Europa League clash with Manchester United in 2017, the Red Devils winning 4-0 on aggregate and ultimately winning the title after a 2-0 victory over Ajax Amsterdam in Stockholm.
