I find much of the bashing on Luiz really unfair tbh. He was not THAT poor yesterday. And even if he were, A. Cole had an awful start, Cahill wasn't much better either, nor was Ivanovic, who's even received a red card (it wasn't a foul imho, but he could have avoided it). Neither I think we can get a better cb than him or cahill easily or for cheap. The best thing we can expect for now is for RDM to find the best defensive system with the players we've got and hope things come together. Maybe then we won't even demand another cb.
