Birmingham's leading shareholder Carson Yeung wants to appoint Steve McManaman and Fan Zhiyi as directors of the Midlands club.
Blues have already been frustrated with Yeung, who failed to carry out his promise to take full control at St Andrews after buying a 29.9% stake in July.
McManaman is a United Kingdom affairs advisor for Hong Kong businessman Yeung, who angered Birmingham co-owner David Sullivan and chairman David Gold after he failed to meet their deadlines to buy the club.
City are making no public comment apart from informing shareholders of the proposal as they are required to do so legally.
But sources close to the club claim they are angry at Yeung's attempt to add two of his associates on to the board after he let them down over the takeover.
One source close to Birmingham said: "Yeung looks to be trying to flex his muscles as the club's biggest single shareholder. He wants to appoint two people to the board, but the owners cannot see the purpose.
"He may have 29% of the club but the control lies with the current board who have 47%. Yeung will not be offered a seat on the board but he appears to be testing their resolve.
"They know they are having a difficult time this season but a lot of the reasons for that are of Yeung's own making. It was Yeung's takeover attempt and the uncertainty of that which eventually saw Steve Bruce leave.
"The board had to appoint a new manager midway through the season so the directors are not very happy with Yeung anyway.
"But to then try and bring two new directors into the club to work with people who've been here 15 years is just being seen as potty. The board will oppose it."
