The 1987–88 "Scudetto" under Arrigo Sacchi marked Maldini's first trophy, and the first of seven league titles, with the club. Nicknamed "The Immortals", Sacchi's Milan side is remembered for including the Dutch trio of Frank Rijkaard, Ruud Gullit and Marco van Basten, as well as the Italian midfielders Carlo Ancelotti, Roberto Donadoni (and later Demetrio Albertini), and a strong defensive lineup. Under Sacchi and later Fabio Capello, Maldini formed with long-timers Franco Baresi, Alessandro Costacurta, Mauro Tassotti, as well as Filippo Galli, Stefano Nava and later Christian Panucci, one of football's strongest defensive quartets of all time. During the 1987–88 Serie A season, Milan only conceded 14 goals, finishing with the best defence in Italy, as they went on to win the Serie A title. Following Baresi's retirement, he also formed a formidable and successful partnership with Alessandro Nesta. Maldini went on to win the 1988 Supercoppa Italiana with Milan the following season, and followed up this trophy with back to back European Cup titles in 1988–89 and 1989–90, while Milan finished in third and in second place in Serie A during those respective seasons. On 19 February 1989, Maldini made his 100th appearance in Serie A.
