Ederson's agent has invited AC Milan to step up their interest in the Lyon midfielder.
The Brazilian has caught the eye with a series of impressive performances since moving to Stade Gerland from Nice in the summer of 2008.
However, speculation has surfaced in recent weeks regarding a possible move to Italy.
Lazio are thought to be interested in Ederson but the 24-year-old's representative Antonio Caliendo believes Milan are firm favourites to win the chase.
Caliendo understands that Rossoneri vice-president Adriano Galliani and director Ariedo Braida could be ready to lodge a bid.
"Adriano Galliani and Ariedo Braida have followed him for about two years," Caliendo told tuttomercatoweb.com.
"I think that, if ever a player had to pick, AC Milan would certainly be in pole position."
