777 had initially aimed to complete its takeover before Christmas but that was pushed back to February, and it is now hoping to get the green light by the end of May.
Now the deal has been thrown into peril after developments in other parts of the 777 business came to light.
On Monday, football publication Josimar reported, external the two main creditors of 777 in Belgium are asking for the seizure of all assets held by the firm in the country after they allege that 777 defaulted on payment deadlines.
On the same day, Belgian publication Le Soir reported, external 777-owned club Standard Liege’s players had not been paid for April and claim that they will not receive payment until the end of the season.
Both claims have been verified by BBC Sport.
Last Friday, 777 Partners and Wander were accused of a “fraudulent scheme” by a lender in a civil court filing in New York.
London-based Leadenhall Capital Partners LLP and Leadenhall Life Insurance Linked Investments Fund PLC claim Wander and 777 ‘pledged’ more than $350m (£279m) in assets as collateral for a credit facility agreement, but alleged that they knew they “did not exist” or were “not actually owned by Wander’s entities”.
Last week, 777 eventually sent a delayed payment of £16m to Everton for day-to-day operational costs – which takes the total it has lent the club to more than £200m – while an airline it owns entered voluntary administration.
Meanwhile, the firm’s UK public relations advisers have stopped representing the company after saying the firm did not meet payments on fees, and it remains to be seen whether they will re-engage.
