AC Milan are tracking Olympique Marseille defender Doria.
Calciomercato.com says Milan have not dropped their interest in the young Brazilian, who was recommended to the club by former coach Clarence Seedorf last season.
Doria moved to Marseille from Botafogo for €5 million, but failed to make an impression under coach Marcelo Bielsa, and is now on-loan with Sao Paulo.
Sao Paulo can buy Doria for the same price, but Milan may intervene to bring the youngster to Italy this summer.
Milan coaching staff believe the defender can emerge as the 'next Thiago Silva'.
