Or maybe common sense. Upgrading Higuain to Ronaldo is easily worth sacrificing one of Caldara or Rugani for if that's what is required. As I said, ideally we could sell Higgy without the sacrifice, but if we can't it's pretty obviously not the end of the world considering the massive improvement to the squad of Ronaldo.
But y'all keep crying like it's the end of the world, I'm sure it will change everything.
