Winning is the only thing that matters, not Sarri being 60, lacking class or whining a lot. If management believes Sarri will turn Juve into a winning machine, they should do it.
Watched Empoli-Napoli clip above, had almost forgotten how much weaker Napoli were pre-Sarri, they were the definition of a home team that can lose to anyone on the road. Back then they actually celebrated 2nd places, nowadays it feels like a meh season for them.
