Personally I am going to have to disagree with you. As of late I believe Luiz has really stepped up his performances, especially against Sunderland where in my eyes he was our MotM. Although he may have had a poor game last night, no chance in hell is he our weakest CB at the moment. In fact I may be inclined to say Terry, he just hasn't looked himself and he didn't exactly cover himself in glory yesterday. At present I would have to say Iva and Luiz are probably our strongest CB pairing, Terry just looks to me that he is off the pace ..... don't know if it is a post injury blip he is going through but for me he hasn't looked anywhere near as commanding as he usually is. Also on the hands behind the back thing he does, surely its to prevent him getting a dodgy handball call against him?!
