Dundee manager Paul Hartley concedes the club run the risk of losing forward Greg Stewart in the current transfer window.
Hartley is still reeling following the departure of striker Kane Hemmings to English League One club Oxford on Wednesday.
The Dark Blues were powerless to stop the 24-year-old's exit after Oxford triggered a £250,000 release clause in his contract.
Hemmings had two years left on his deal while fellow PFA Scotland Player of the Year nominee Stewart has entered the final season of his contract.
And Hartley fears the former Cowdenbeath striker may be tempted to leave Dens Park if an offer comes in for his services.
Hartley said: "Who knows? When you've got someone who has been doing so well over the last two years, with the amount of goals and his performances, then there's always the possibility.
"And players have got ambition also, we have got to consider that. Do we want to keep our best players? Of course we do but the harsh reality of football sometimes, you can't always keep them.
"We have just got to try and find other good players and that's my job, to find a replacement as soon as we can.
"It's not going to be easy, there's not many strikers out there that can guarantee you 20-25 goals a season. It's up to myself and my staff to find someone and we are working hard behind the scenes."
Hartley has yet to discover how much of the transfer fee from the sale of Hemmings will be available as he looks for a replacement.
"We'll have a conversation with the owners in the next couple of days. We have four or five weeks until the window shuts and we have to find the right person," Hartley said.
