I feel only Madrid and Juve are real alternatives for De Ligt. Both can afford the potentially deadly wage (genuinely don't think Barca can) and the crazy fee (dont think PSG can) and both have a potential spot in their centre of the defense that De Ligt may get the game time he needs. That being said Ramos is unlikely to leave, even if wants it and they just signed the guy from Porto for 50m. They may move for a more low profile CB than De Ligt who wont make as much noise or take up a vital chunk of the transfer budget. Juventus just have Rugani (seem less and less interested in him every season), Bonucci and Chiellini both getting worse with their age.
