 The following season, he transferred to the defending UEFA Cup and Coppa Italia champions Parma for an astounding €30 million.Although the team started the season strongly, winning the 1999 Supercoppa Italiana, Parma never quite fulfilled their potential to win the league title, and Amoroso was not able to match the form he managed with Udinese due to recurring injury problems; the club did manage to reach the 2001 Coppa Italia final, however.After two seasons, Amoroso was soon on the move again, this time to Borussia Dortmund in Germany, for 50 million Deutsche Mark (€25 million), a German record at that time, and as of 2017, still a fifth highest signing after Corentin Tolisso, Javi Martínez, Mario Gómez, and Mario Götze.
