Luiz hugely improves our passing from the back. Which was pitiful at times last season. A lot of our defensive issues were caused by this. Getting pressed into errors constantly. The rest of his game can be a bit erratic, but probably no worse than Mustafi and co. In all honesty, we were never going to land a massive CB signing in this window with our current budget. We’ve done quite well overall. Getting Pepe was a huge bonus.
