At the start of the season, Luiz was probably our best defender. He and Terry seemed to have an understanding, then came all the injuries and suspension...and Luiz just started playing shit with Cahill. Luiz makes mistakes and Cahill's an average defender who also makes mistakes..put the two of them together and you're left with one of our worst CB pairings of recent times. I don't get why RDM persists in using the Luiz - Cahill pairing. I mean unless Brana needs a rest or he's injured, use Brana - Cahill...and when JT gets back, play him with Luiz.
