Chivu or Milito aren't the type of players would provide cover at CB, cover would have to be from someone at the tail-end of their career or just starting it. You're wrong about Lahm too, he's just had a mediocre season and wasn't even all that impressive at the World Cup, I think he's too small and tends to cut inside too much. I'd prefer Simao and Mancini out of those two, but I'm not sure we need two. That's mostly because I think we'll see Gerrard on the right more often and because Kewell is back (for now at least).
