Question: ACF Fiorentina returned to Serie A, following of how long of an absence, after the bankruptcy of the previous incarnation of the club, Javier García Portillo, a Spanish retired footballer who played as a forward, were among the highly rated players to sign up for Fiorentina, either permanently or on loan?
Sentence (from "2004–05 ACF Fiorentina season"): Fiorentina returned only due to the expansion in terms of the number of top-league teams, and therefore had to significantly strengthen the squad in pre-season.
Relevant evidence: No
