De Ligt belongs in the special class of centerbacks that can complement practically anyone because of how well rounded their skill-set is (he has already played with different types of centerbacks in his career: Sánchez and Wöber to Van Dijk and Blind and even De Jong). Think along the lines of someone like Nesta, who had no problems excelling with a bunch of defenders — Mihajlović, Couto, Costacurta, Maldini, Cannavaro, Stam, Thiago. With the way football is progressing, having two centerbacks who are comfortable on the ball is becoming a bit of a norm at the elite level, and Lindelöf + De Ligt would be a very smooth partnership from that standpoint. And despite having the technical skill-set of a sweeper, De Ligt is fairly robust and very precise with his duels/tackles, so it wouldn't be a lightweight partnership by any means, especially with Shaw at leftback to further solidify things. Barring injuries, you could argue that he's the safest elite prospect in recent years with Mbappé; should be a no-brainer for United but the competition will be intense (especially from Juventus: who have a solid relationship with Raiola, as well as the usual Spanish suspects, among others).
