Morfeo's precocious performances led to a move to Fiorentina in 1997, for an undisclosed fee. During his time in Florence, despite the presence of the attacking trio of Manuel Rui Costa, Gabriel Batistuta and Luís Oliveira on the team, he initially managed to find space in the starting eleven under manager Alberto Malesani, although following the arrival of Edmundo, he later struggled to find playing time; in spite of the competition for a starting spot, he still managed 5 goals in 26 appearances for the club, and also provided several assists for his teammates throughout the season.
