Frederic Piquionne says he does not expect to play for St Etienne again.
The French striker has been a January transfer target for Lyon as boss Gerard Houllier looks to strengthen his attacking options.
However, Les Verts are unwilling to allow Piquionne to move to the Stade Gerland, to the dismay of the player.
Piquionne feels he has become stuck in the middle of the rivalry between Lyon and St Etienne.
"I do understand that they want to hold onto my future, to hold onto my career," Piquionne told Sport24.
"That is why I used the word slave. I didn't use that word because of my salary, I know that I earn a lot, I am not stupid.
"I just want to say I am the victim of the rivalry between Lyon and St Etienne.
"I will go to training, do what I am asked, but I know I will never play again with a St Etienne shirt on.
"I can't understand how inhuman people can be. (Co-chairman) Roland Romeyer made cruel remarks to me. He made me look like goods.
"I know what St Etienne represents, its people. I don't swipe at the green shirt, but I think the directors haven't been right with me.
"I am not sure if I will join Lyon. But I think that if another club had made an offer, I would already have left."
Lyon chairman Jean-Michel Aulas has not given up hope of landing Piquionne, but may look at other alternatives.
"I don't have bad words for the St Etienne officials, but when you are managing a big club the relationships with your players have to be attended to.
"Gerard Houllier really wants Piquionne, but if it is not possible we will try to sign one or two other players."
With the uncertainty over Piquionne's future, St Etienne may move for Nice striker Matt Moussilou.
