It’s an interesting one going forward. I don’t think we should hurry it, though, and remember that Maguire is just learning to know the team. I think it’s important for Maguire to get settled together with an intelligent and somewhat experienced partner who has played with De Gea, Shaw and Pogba for a while, and had a full preseason of being leading CB in how we are going to play. Quite a few of Maguire’s decisions so far shows that he isn’t bedded in enough yet to be the leader of a completely new and young back four, especially when the front six is so vulnerable/inexperienced. I think it makes sense to build from Lindelöf/Maguire, and phase Tuanzebe slowly in as the first replacement in cups and injuries.
It’s easier for a young player to be phazed into a back four that is secure in their roles rather than finding their roles. I think this is easier accomplished with Lindelöf/Maguire as a building platform, and that Tuanzebe will benefit from it as well.
But then again, what do I know?
