Incoming Fulham manager Martin Jol wants transfer funding assurances before taking the job.
The Daily Mail says Jol is seeking clarification that he will be given a competitive war-chest to strengthen the squad.
Owner Mohamed Al Fayed is likely to give him a healthy budget in an attempt to seal his appointment.
The Egyptian businessman was ready to back Hughes to the tune of £10m to sign Espanyol striker Pablo Daniel Osvaldo this summer.
With Jol currently unattached, Fulham will not need to fork out a hefty compensation fee to prise him away from another club which will count in his favour for the transfer budget.
