Manager Keith Curle says Carlisle United are yet to receive an official bid for midfielder Kyle Dempsey, although Barnsley have made enquiries.
Dempsey, 19, has scored five goals in 17 games for the Cumbrians this season, prompting reported interest in the player from other clubs.
Curle has also recently fielded questions about Brad Potts's future.
"We've not had an official offer for any of our players in writing," Curle told BBC Radio Cumbria.
The approach from Barnsley is a new revelation from former Notts County and Torquay boss Curle.
He said: "We've had an enquiry from Barnsley.
"A representative of the club rang [managing director] John Nixon and he asked Barnsley to make it official by putting it in writing.
"As of yet we haven't received anything."
