I don't want to come across as wizened and cynical here, as I really have no idea how these things work, but how much influence do you think De Ligt has on the process if you, presumably, have to get through his agent first? He'll go where he's told to go.
PSG, top dollar all round and a permanent (cushty) seat at the top table, even if they do seem prone to bottling matters of importance (what's that to him, he's Dutch). It's not like he's going to China.
