As much as Luiz has done well in the pivot so far, we have gotta remember that he has played there only against Monterrey and Villa, no disrespect to them. They are not the toughest of oppositions and were pretty poor on the day we played them. No doubt Luiz has shown positives playing in that role but he needs to be tested against better quality oppositions first before we can officially say 'Luiz CAN play in the pivot'.
