Marseille are hoping to have their new coach in place within the next week.
Former Congo coach Claude Le Roy is favourite to be appointed after Didier Deschamps turned down the opportunity and his agent has confirmed the club have been in contact.
However, Le Roy is currently in negotiations with the South African football association about becoming their new national team coach.
"There has been direct contact," Gael Mahe confirmed.
"Claude was born in Marseille and has the club close to his heart and he won't rule out Marseille's proposition.
"There are several offers on the table, from national teams in Africa, Asia and Europe as well as clubs in Europe."
French under-21 coach Rene Girard is also thought to be a possible successor to Jean Fernandez, however, the tactician has denied any contact with l'OM.
"I am flattered by the interest from Marseille but nothing has started yet," insisted Girard.
"After the European championships, I will listen to people. My phone isn't switched on, I am focusing on the championships.
"I am flattered, it is a form of recognition. I am from the south, I love that region.
"We will see what happens next week."
Meanwhile, the club are hoping to complete the signing of Brazilian midfielder Marcinho Guerreiro in the coming days.
Guerreiro has already passed a medical in France and agreed personal terms but l'OM have yet to agree a transfer fee with his current club Palmeiras.
On loan duo Toifilou Maoulida and Renato Civelli will definitely be playing their football at Marseille next season after sealing permanent switches from Monaco and Banfield respectively.
