 Milan vice-president Adriano Galliani stated that Fiori's lengthy stint at the club, despite his lack of playing time, was due to his professional conduct.Before AC Milan, he played for Lodigiani (one season), Lazio (6 seasons), Cagliari (three seasons), Cesena, Fiorentina and Piacenza (1 season apiece).It was because of his impressive performances with Piacenza that Milan decided to sign him, although at the time they already had Sebastiano Rossi and Christian Abbiati in their ranks.
