This guy is very reliable, as far as I know.
Translation (thanks reddit): Amavi has agreed to join Marseille on a 4 year contract. €2m for loan and €8m to make the move permanent. OM hope to finalize deal within 48 hours
4 years contract while he is only loaned sounds weird, but I guess its a one-year loan + a three-year contract afterwards (maybe there is an obligation to buy him)
