You're right, i do remember you defending his signing and it does not matter if you view him as a squad player or not, i'm just tired of people blaming others for Luiz's mistakes. Luiz lost the ball for the Man utd goal, most of the blame is on him, not Cahill for not being in the right positon - when he actually was or not stopping Hernandez - when all that would have resulted to was a red card. We all know Luiz is a good defender, he showed it many times last season, but these silly uncalled for mistakes are the difference between winning and losing big games. Even when he plays well, you just know he will at least fuck up once - check Newcastle game this season. It's for this and only this i prefer Cahill to him. It's not because Cahill is so much better, like i said already, he also makes mistakes, so does JT - but you will rarely see both make the kinds of mistakes Luiz does over and over.
