In 2023 Napoli won Serie A by 16 points. One year later, they finished ninth.
90 points, 28 wins, 4 defeats. Then 53 points: the odds, game by game, had expected 68.
How often do champions defend their title? In Europe's top five leagues over the last 11 seasons: 28 times out of 55. Barely half. On average, champions drop about 8 points the following season.
Winning the title is hard. Keeping it is harder.
