Carsen Yeung is planning to raise fresh funds for Birmingham City.
The Guardian says Yeung is preparing to mortgage his private properties in a cash-raising exercise.
Birmingham won their first major trophy since 1963 on Sunday with their Carling Cup final victory over Arsenal. However, the club's parent company, Birmingham International Holdings, has made a regulatory announcement to the Hong Kong stock exchange explaining that Yeung must take extreme measures to keep the club solvent.
It said: "Yeung [is applying for] a credit facility line of no less than HK$150m [£11.8m] with a bank in three tranches with his private property located in Hong Kong as the asset pledge.
"Yeung has agreed in writing that he will use this credit facility to finance the company and the group in order to provide sufficient financial resources to the group so as to enable the group to meet its liabilities as they fall due."
