The next season (2005–06) started with the arrival of a new owner, Giuseppe Ruggieri, and a new manager, Antonio Soda. After a long battle for the first position with rivals Genoa C.F.C., Spezia were crowned Serie C1 champion and promoted to Serie B after 55 years of absence. The squad included Vito Grieco, Massimiliano Guidetti, Giuseppe Alessi, Massimiliano Varricchio and Roberto Maltagliati. Life in a Serie B with powerhouses Juventus, Genoa C.F.C. and S.S.C. Napoli was difficult for the newly promoted Ligurian side, which themselves were fighting to avoid the relegation spots. With mid-season signing Guilherme do Prado, Tomás Guzmán, Corrado Colombo, the old member Massimiliano Guidetti's good form and Nicola Santoni, Spezia survived in Serie B, gaining participation in the playout round after a late 3–2 victory in Turin against Juventus. Spezia then survived by winning the playout round against Hellas Verona. But in the next season, with Isah Eliakwu, Colombo and Do Prado, the club failed to make the miracle happened twice, primarily due to a troubled situation in the financies of the club.
