The England international has attracted interest from a host of Premier League clubs, including Arsenal, Fulham and Liverpool.
With Birmingham facing the prospect of possible administration, chairman Peter Pannu is hoping the club will be able to raise funds to ease the crisis at St Andrew’s.
But despite mounting speculation about the 19-year-old shot-stopper’s future at the Championship club, there have been no concrete bids for the Birmingham teenager.
“No-one is for sale and everyone is available,” Pannu told the Birmingham Mail.
“My top priority now – and if I do offend anyone, I care not – is to make sure this clubs stays afloat.
“I will do what I have to do and buy some time to ensure that I can hand this club over to good people who can take us to the next level.”
Birmingham manager Lee Clark revealed that he would like to keep Butland but is unsure if the up-and-coming England star will remain at the club beyond January.
“Whether we will keep him, I honestly don’t know,” said Clark.
“The only official bid the club have had in terms of a written bid or a verbal bid is the one that was turned down in the summer from Southampton just as I was taking the job.
“That’s not to say we haven’t had lots of interest in Jack and people asking the question.
“But in terms of somebody actually putting down that they want to take him and what they’re willing to pay, that hasn’t materialised.”
