Carson Yeung has been told to bid for Birmingham City by Friday - at the latest.

Yeung has come under pressure from his own British stockbrokers to make a formal offer for Blues.

London-based investment bank Seymour Pierce have laid it on the line to the Hong Kong tycoon and told him to bid for Blues by Friday at the latest, according to City sources, says the Birmingham Mail.

At the EGM of Grandtop International - the company through which Yeung is trying to buy Blues - it was agreed to press ahead with a full takeover attempt.

Yeung holds 29.9 per cent of the club - a shareholding sold to him by David Sullivan, the Gold brothers, Karren Brady and Roger Bannister in the summer.

But it is believed Seymour Pierce have stressed to him he must show proof he has the £35million needed in the next couple of days in order to meet the December deadline laid down by Blues.
