I still dont agree with that we need another defender. Jones, Smalling, Evans, Blackett, Rojo, Blind, even Carrick can play CB. Rafael, Shaw and Valencia arent bad. Any club that loses players of Ferdinand, Evra and Vidic quality and experience will take a while to adjust. I can imagine that even in their later years when they werent playing, they would have been immense in the changing room for the others.
Fully agree with this LVG quote:
"I don't think it is the weakness of our defence, it is the weakness of our defensive organisation. We have to do that better."
