AC Milan's sale to Sino-Europe will now occur in February.
There appears to be no sign of the Chinese government authorising the necessary transfer of funds from the country.
Sky Italia says the date for closing will now be pushed back, with the takeover to be completed by the end of February.
A further deposit of €100m is expected by December 13, to show the good faith of Sino-Europe and potentially provide the Diavolo with funds for the transfer market.
