The 19-year-old is highly regarded after making his England debut against Italy in August and has been linked with a move to Premier League sides Liverpool, Newcastle United and Southampton.
BBC West Midlands said the club, who are 20th in the 24-team division, had confirmed they were willing to let first-team players leave as the search goes on for new owners.
Current owner, Hong Kong businessman Carson Yeung, had his November trial date for money laundering deferred until April by a court in his homeland.

Serbian striker Nikola Zigic and the club's leading scorer this season, Marlon King, are others who could leave.
