It often seems forgotten that there is a bit more to winnign football games (or even not losing them from winning positions) than just which players a director of football assembles.
We could still lose games if Luiz or another comes, it is not entirely simply victory by formula.
Teams with better midfielders than ours lose games and some with worse players win them. It happens.
By all means I want us to address it, don't get me wrong. But we still have to find ways to win or hang onto leads, and this group should have it in them to do that.
