Yeah thats very true... i think it will be FdJ or no one, but only because ten Hag is very confident that he'll get de Jong.
I think it also depends on how desperate Barca get. If after a couple of weeks, it looks like de Jong isn't going to budge, they might start to worry and just cough up and pay what he's asking. Alternatively, de Jong might get frustrated with not flaying or being used as a backup in an unfavoured position, think it's not worth it anymore and just decide enough is enough, he wants out. It really is who blinks first
