Ederson's agent feels the Lyon player is being ostracised by manager Remi Garde because of his contract situation.
The 26-year-old is out of contract in the summer and has only started one league game this year and five all season.
And Antonio Caliendo feels his client is being forced into signing a new deal at the Stade de Gerland just to get a chance to play.
"Right now we are very far from the agreement for the extension, and I feel that the coach has taken the decision not to play him from the start until he signs a new deal," Caliendo told tottomercatoweb.com.
"This situation makes me very angry because we don't accept blackmails. At this time there are several clubs interested in him like Juventus, Inter, Santos and Lazio who have been following for the past five seasons."
