Inter and OM have been worn for several weeks for a fee for the former real betis star.
Sky Italia says that an agreement has now been made with a reimbursement of € 23 million plus € 2 million in bonuses.
The breakthrough came last week when interpresident Beppe Marotta met face-to-face with Marseille counterpart Pablo Longoria.
Inter expects forms to be filled and signed before the club World Cup is the deadline next week.
