Crystal Palace manager Roy Hodgson insists Wilfried Zaha is not for sale in January.
Palace forward Zaha, whose contract runs until 2023, failed to force a move away from Selhurst Park during the summer after handing in a transfer request.
The 27-year-old has been linked with Premier League rivals Everton, Arsenal and Chelsea in recent months and his future will once again come under the spotlight when the transfer window opens on New Year's Day.
Eagles boss Hodgson admits any genuine bids for Zaha must be considered by Palace's board but is certain the club do not wish to sell.
"Wilf is not for sale, so basically I don't need assurances. We aren't trying to sell Wilfried Zaha, we want to keep Wilfried Zaha," said Hodgson.
"What assurance can people give? I have the assurance there is no one in the club that wants to sell Wilfried Zaha.
"But of course you never know where bids are going to come from and I suppose every time there is a serious bid for one of your players the board of directors needs to take it seriously.
"It's certainly not something we're looking for."
