More the fault of the PSG staff then for bringing him on. This isn't the last knocking of the French cup, this the CL where every decision counts vitally. If he was not fit he shouldn't make the bench, no excuses and they have enough so called quality to field a fit player and switch things around rather than bring on Luiz and watch him get murdered. A fully fit Luiz is a worry, a half fit Luiz is like a fucking disaster.
