The agreement, as stated by Barça in January when Todibo returned to France on loan, will be worth an initial €8.5 million, with another €7m due in potential add-ons.
If finally confirmed, it will be a successful piece of business for Barça, who signed Todibo from Toulouse for around €1m.
Todibo has a contract until 2023 and will be the second player to leave Barça this summer after Juan Miranda, with Konrad de la Fuente also close to a move to French side Marseille.
Italian transfer expert Fabrizio Romano reports Barcelona are close to now selling Todibo to OGCN.
