The 24-year-old striker is currently on Africa Cup of Nations duty with Ivory Coast in South Africa, but has been in scintillating form for the Dutch club this campaign.
With 16 goals in 18 Eredivisie appearances this season, Bony has attracted admiring glances from a host of potential suitors, with Liverpool boss Brendan Rodgers reportedly considering an attempt to lure the player to Anfield.
However, interim Chelsea manager Rafa Benitez has also been linked with a move for the African forward, despite already adding Demba Ba to his Stamford Bridge squad this month.
Bony is under contract with Vitesse until 2015, but Chelsea and Liverpool have both been given hope of securing his signature, after general manager Erwin Kasakowski, revealed he would not stand in the way of a move if a big club came calling.
"We have promised Wilfried that we will consider any serious offers from him that would take him a step higher," he told AD. "But it must be good for both parties.
"Currently we have received no bids, and frankly we would rather Wilfried stays."
CSKA Moscow are another club reportedly interested in signing Bony, and the Russian club might also make an offer before the January deadline next week.
