The 19-year-old goalkeeper was the subject of a failed £6 million bid from Southampton in the summer, but could move on in order to help the Blues balance the books
Birmingham goalkeeper Jack Butland has admitted he could be sold to ease the club's current financial woes.
The Championship side's owner Carson Yeung is currently facing money-laundering charges, which has subsequently led to his assets being frozen.
Yeung has been unable to fund Birmingham since their relegation from the Premier League 18 months ago, but former QPR chairman Gianni Paladini is attempting to finalise a takeover.
Butland told the Daily Mirror: "You can talk about it, but there's nothing we can do about it as players.

"We can only control what we do on the pitch and what we do on the training ground.
"What happens with the board, with the owners and a possible takeover is meaningless until something actually does happen."
Butland, who has one senior England capand represented Great Britain at the 2012 Olympic Games, was the subject of a failed £6 million bid from Southampton during the summer transfer window.
Everton are also rumoured to be interested in the 19-year-old as a long-term replacement for current goalkeeper Tim Howard.
