Didn't see the first 55 minutes but he looked really shaky what I did see. I think at that point the game was farcical and open, shit conditions, the whole team not contributing anything from a defensive POV, and it just exposed him against fast players again and again. A defender like Caceres would have suited that role better, Rugani likes to keep things calm and keep the goal to his back, not go chasing people around the wider areas of the pitch. I still think he'd be much better with a run in a back four, but he's a kid so can't be expected to be brilliant right now.
