You've misunderstood my post. I think Zinchencko is special. I thought this long before it became obvious to the popular majority.
I think he'll mostly play at Leftback because that's his position at City. And there is even more competition in the middle. We will likely have Rodri, Fernandihno and Gundogan who can play 6, then we have Kevin, Dave, Gundogan, Phil, and Bernado who can play 8. Pep has hinted that Riyad can play 8 too.
So when fans say he can get games in the middle, they are really not thinking it through.
I think he'll start the season as the starter at LB backed up by Angelino. Mendy I don't expect to be ready for the beginning of the season. I sense that's probably part of the reasoning behind bringing Angelino back.
