Sheffield United boss Chris Wilder admits he cannot stop his best players from leaving.
The Blades are hoping to retain the core of the group that has seen them fly so high in the Premier League.
While they may lose Dean Henderson, who is on loan from Manchester United, Wilder is also skeptical of the possibility of keeping the stars who are contracted to the club for the next few years.
"We are still a selling club, but we are a more powerful one," he told reporters.
"We are a better one on the pitch, we can attract better players now.
"I still think - from a wages point of view and financial point of view - if any of the big clubs came calling for any of our players then I can't stand in their way.
"It is difficult, if anyone is wanting to double players' wages and stuff like that. Buying club, selling club, there are always three parties in a transfer and we have to recognise our power in that three.
"Nobody is going to put a gun to our heads for small offers for players we rate and value. It will be market value if anything happens. Nothing has happened, no one has rang me yet."
