He was never a master passer, but in the Ajax system with Blind, Schone, Frenkie, Mazraoui and Ziyech closely around him in build up all he needed to do was give them the ball.. It was not expected from him. I can imagine that in a system where you have fewer passers around you, that the shortcomings become more visible.. De Ligt was great in leading the defense and more than capable of doing in possession what was expected of him, meaning give the ball to one of the many creative players around him.
Same for Donny in that Ajax side.. Donny was never a creator, but had Ziyech, Schone, Frenkie, Tadic, Neres around him to deliver the ball in the box.. All Donny needed to do was play in combination deeper on the pitch and get in the box when the ball was there and he was great at that for us.. If you expect him to be creative on the ball as a potential Bruno replacement, purely because has is at #10, you are going to be very disappointed.
If you expect De Ligt to be the creative mastermind in build up, you will be dissapointed. If you surround him with players who will do that and you expect him to lead the defense, thats something you could expect from him..
