The 24-year-old, who has made 187 French League 1 appearances and scored nine goals in six years at Nancy, is already attracting interest from a number of clubs, including Manchester City, Sevilla and Real Betis, after declaring a wish to leave.
He said: "My agent is in discussions with Betis, but I am aware of an English club keen to acquire me. I don't want to be at Nancy next season, as I've done enough there. I want to test myself in a top European league."
Therefore Curbishley will need to act quickly if he would like to take Chretien to the Hammers and the player could cost in the region of £3.5million given that his current Nancy deal does not expire until summer 2010.
