1989-90 of the Serie A was another dominant year for Napoli, with Diego Maradona being among the leading goalscorers in Serie A (16 goals), behind Marco van Basten of Milan (19 goals) and Roberto Baggio of Fiorentina (17 goals). But while Baggio's Fiorentina narrowly avoided relegation, Maradona's Napoli won their second Serie A title in four seasons, while Van Basten helped AC Milan retain the European Cup as compensation for their failure to win the Serie A title, having finished two points behind Napoli. Going down to Serie B were Udinese, Verona, Cremonese and Ascoli.
