A lot can happen in a week : Gunners

A slightly less spoken about topic: our centre back situation is dire, and I understand some comments defending the Luiz contract extension as a short term solution rather than have to spend an additional 15-20mill. But why don’t we have an youth CBs? This is a time where we should have at least one semi decent youth player in every position. I don’t expect a generational talent or wonderkid, but at least someone to make extending the contract who had an absolute trainwreck of a game less than a week ago seem like a bad idea.
