The 1989–90 Serie A season was another successful year for Napoli, with Diego Maradona being among the leading goalscorers in Serie A (16 goals), behind Marco van BastenofMilan (19 goals) and Roberto BaggioofFiorentina (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 Milan retain the European Cup as compensation for their failure to win the Serie A title, having finished two points behind Napoli. Demoted to Serie B for 1990–91 were Udinese, Hellas Verona, Cremonese and Ascoli. In Europe, Sampdoria won the Cup Winners Cup and Juventus the UEFA Cup, making this year the most successful in Italian football history.
