The 26-year-old is expected to seal a switch to the Stade Velodrome next week after the club confirmed they were in the final stages of the negotiation process
The 26-year-old will reportedly undergo a medical with the French giants next week ahead of sealing his switch to the Stade Velodrome.
Earlier this month Payet's agent was forced to deny OM had made a bid for his client, but the Ligue 1 runners-up have now confirmed they are close to finalising a deal for the France international by releasing a statement via its official website.
They said: "Olympique de Marseille has reached an agreement in principle with Lille regarding Dimitri Payet's arrival to the club."
Payet, who joined Lille from Saint-Etienne in 2011, is contracted to les Dogues until 2015.
