I think they will still need to make more transfers before the end of the transfer window. Aubameyang sale looks very likely as Barcelona has communicated their price to Chelsea which is said to be around £30m, this will be a major profit they will make from this sale for a player signed on a free move from Arsenal. The reasons for the sales seems fulfilled but I heard Kounde has still not been registered due to financial shortcomings so some players will still have to go to get more money.
On the other hand they also have to immediately pay De Jong's salary arrears so that he is ready to be sold because for now he does not want to be sold until his salary is actually paid by Barcelona.
And when he's not for sale, it's obviously not good enough because he is one of the most expensive players who can be used as an option in the midst of their current financial storm.
Right now, De Jong is the biggest headache for Barcelona they want to offload him, but there are few transfer issues which are not solving and players don't want to leave the club without solving them, which is his right.
Arrears are needed to settle as they already committed with player at the transfer time but now trying to cut this all is surely not good for reputation of club like Barcelona if they end this all with mutual understanding then surely he is ready to join Chelsea which could be big financial win for them, and they can do much better things with this all.
Memphis Deepay is also in limelight right now and Juventus is also in direct talk with this player which mean currently their main focus is bringing their salary bill under control which is surely creating serious trouble for some time.
