Wilfried Bony remains keen on a move away from Vitesse Arnhem, but has seen talks regarding a switch to Aston Villa hit a stumbling block.
A loan agreement with the view to a permanent deal being struck at a later date was reached with Villa on Thursday, but Vitesse have now altered their stance.
The Eredivisie side claim they are only willing to discuss a sale, leaving Bony facing up to an uncertain future.
The Ivory Coast international striker has expressed his anger at seeing discussions with Villa break down, while his representative has slammed Vitesse for their handling of the situation.
Bony told De Telegraaf: "This club drives me completely crazy. Yesterday they blocked a transfer to Aston Villa."
His agent, Francis Kacou, added: "Wilfried is unhappy at Vitesse.
"Aston Villa wanted to loan him with an option to buy. The deal would net Vitesse almost €10million (£7.9m).
"Yesterday they agreed to that, but in the evening they stated only a permanent deal is possible. We have everything arranged and were planning to leave for Birmingham. Unbelievable.
"Wilfried has to leave Vitesse. He is looking for a new challenge on a higher level.
"Vitesse say they are ambitious, but I don't see that. Wilfried is surrounded by bad players and because of that he can't develop himself any further."
