Grenoble general director Pierre Wantiez says young forward Sofiane Feghouli can leave for the right price.
Manchester United had scouts watch the 19 year-old in January, with the player delighted by the prospect of a future move to England.
"Our transfers will also depend on the sale of players," Wantiez told the Dauphine Libere.
"Today Feghouli is the only one who could move on. He has expressed the desire to embark on a new challenge and that is the moment for him.
"If a reasonable offer is made, then we will see. But movements on the market will start later than usually because of the crisis."
