There is still no guarantee that the move will go ahead, despite Manchester United agreeing a £63m deal with Barcelona.
They know what they have to pay for the manager, with a bigger up-front payment and more add-ons.
The 25-year-old is in a contract dispute.
Deferred payments that were included in the new four-year deal are at the center of the dispute.
According to reports in Spain, Barcelona have told De Jong to leave for financial reasons.
The deferred payments on his contract make him reluctant to leave Barcelona without an agreement over his exit terms.
Should De Jong not join, United are willing to give the situation more time to work out.
The club is unsure if the player will come back to training.
His options have been reduced since it was confirmed that he won't be joining the Blues.
The player is thought to want to keep playing at the highest level, despite reports of a huge offer from Saudi Arabia.
