Del Piero began the following campaign strongly by winning the 1997 Supercoppa Italiana, forming a strong offensive unit with Juventus teammates Zinedine Zidane in midfield, and newcomer Filippo Inzaghi upfront. The 1997–98 Serie A campaign was his best season yet, as he scored a joint career best of 21 goals in Serie A, and finished top scorer in the 1997–98 UEFA Champions League with 10 goals, one of which included a freekick and a hat-trick against Monaco in the semi-finals. With these goals, he helped Juventus to reach their third consecutive Champions League final, although Del Piero was not fully fit for the match, and Juventus were once again defeated, falling 1–0 to Real Madrid from a strike by Predrag Mijatović on 20 May. Domestic success, however, was achieved that season, after a tight battle with Inter Milan, as Juventus celebrated its 25th Serie A title over their Italian rivals, with Del Piero scoring a memorable and decisive individual match-winning goal during the controversial Derby d'Italia match. Del Piero also managed a goal in the 1997–98 Coppa Italia that season, helping Juventus to the semi-finals, and finishing the season with a career best of 32 goals in all competitions. Del Piero was awarded the Serie A Italian Footballer of the Year award for his performances, and he was also nominated for the 1998 Ballon d'Or. During this time, he was nicknamed by the fans as "Il Fenomeno Vero" ("The Real Phenomenon"), in comparison with the Brazilian striker Ronaldo, who was nicknamed "Il Fenomeno" ("The Phenom") by supporters of rivals Inter Milan.
