On a serious note, I think if we qualify for the CL next season, we'll have a very good chance of signing FdJ next summer. I'm fairly sure that he's going to spend much of this season sitting on the bench and despite what Barca fans might say, I don't think this Barca team are quite as good as they think they are, will probably get their backsides handed to them in either the Last 16 or the QFs of the CL. Despite Barca being his dream club, I can't imagine Frenkie will want to sit around as a sub for a good but not great team.
Then when you look at other buyers, Real are the only other club in Spain capable of affording him but Barca won't sell to Real. The Italian sides don't have the money to buy de Jong. PSG could potentially buy him but they seem to have a new "Buy French" policy plus already have Verratti and Fabian Ruiz. Bayern in theory could have the money to buy him but they never really spend that big, he would ruin their wage structure, plus they already have Kimmich, Goretzka, Sabitzer, Gravenberch, and probably Laimer on a free next year. I can't see either Spurs or Arsenal signing him. I could see Chelsea signing him but I think they won't qualify for the CL next season. He'd ruin Liverpool's wage structure, it would be impossible to cover both him and TAA defensively, and they seem set on Bellingham. City don't tend to play a 4-2-3-1 (They have Rodri already, why sign FdJ when you can genuinely play with two Free 8s?) so he doesn't make sense for them. Put that altogether and if Utd make the CL, we should have a good chance of signing FdJ next summer.
