Yesterday, Gomis was in Marseille to complete his medical examinations and has signed a contract, claims L’Equipe on Friday.
The 30-year-old is now expected to fly to Halle in Germany to join his new teammates for pre-season training.
The Ligue 1 club had agreed a loan deal for Gomis, but won’t have a right of redemption to buy him at the end of next season.
Marseille have agreed to pay 60% of his wages, which is around €5m/season.
Gomis has spent most of the time on the bench after the arrival of Francesco Guidolin, and was expected to leave the club this summer.
