Deserved win, could have scored 8 or 9 goals, very unlucky not to. Sarri still cant be judged, if putting Emre Can on the field was his decision, then he takes some of the blame for letting a very poor Napoli back into the game. Their goals were pure luck, De Ligt was expected to make a major fuck up, he is of course not ready to play for a top club, his amateurish display for Napolis second goal is laughable at least, same can be said for their third.
Things got back to normal at the end, Napoli didnt do enough to show that they have what it takes not to lose against extremely superior team and eventually lost. Shame it had to be with a ridiculous own goal, but that game alone sums up their last 2-3 seasons, they have only themselves to blame.
