Neil Redfearn has taken heart from Leeds' claims that their young first-team players will not be sold in the summer.
Blackburn midfielder David Dunn has confirmed his 27-year association with the club will end in the summer.
Barnsley have drafted in England international goalkeeper Jack Butland on loan from Stoke as cover for the injured Luke Steele.
Steele sustained a back injury in training this week and will undergo a scan to determine the full extent of the problem, so Butland will make his debut for the club at Leicester on Saturday.
Butland, who made his senior England debut against Italy last year, has been signed on an emergency 93-day loan.
The 20-year-old, who started his career at Birmingham, was signed by Stoke for a reported £3.5million in January.
Wigan veteran Mike Pollitt recently made three first-team appearances for Barnsley while on loan, but returned to his parent club.
