Reggina Calcio did renew its Serie A contract on the second consecutive occasion, ensuring the longest stay of the Calabrian club in the top division of Italian football. With returning coach Franco Colomba not being successful in his third stay at the club, Giancarlo Camolese guided the side to 13th place in the league. With only 29 goals scored, Reggina relied heavily on its defence for the survival, and Martin Jiránek plus defensive midfielder Davide Baiocco strengthened their reputations. After the season, Baiocco returned to Juventus, who in turn loaned him out to Reggina's arch-rivals Messina, newcomers for the 2004–05 season, setting up the first Messina strait derby in the highest division ever.
