Birmingham City Chairman David Gold says he is less confident about Hong Kong businessman Carson Yeung's ability to take full control of the club.
Yeung has to find another £30m to buy out Gold and David Sullivan, and has until 23 December to do it.
Gold told the Birmingham Mail: "I just don't have the same confidence that I had two weeks ago, and I think David Sullivan feels the same.
"Only Carson Yeung can pull out of this, by failing to meet the deadline."
