Media reports over the weekend had suggested that Blues were in talks with an unnamed foreign businessman about the sale of the club and this has now been confirmed.
"The directors have noted the recent movement in the share price and the press speculation and confirm that they have had an approach with regard to a possible acquisition of the issued share capital which may or may not lead to an offer for the company," a club statement on the official website reads.
"Such discussions are at a very preliminary stage and the directors note that there is no certainty that a transaction will result from the approach."
