The agent of Vitesse Arnhem striker Wilfried Bony admits he could move in January.
Bony has been linked with Chelsea and Liverpool this season.
"Bony has a contract, so Vitesse is in quite a strong position, but if a big club comes, then he could be off. I consider the chance in the winter market not as big as at the end of the season," said Louis Laros.
"But if the interest increases and it also known to the player, it is very difficult to keep him calm."
