During the 1955–56 Serie A season, Cervato won the Serie A title ("Scudetto") with Fiorentina as the club's captain, his only title with the club; the 1955–56 title-winning side under Fulvio Bernardini lost just one game – the last one at Genoa – and is regarded as one of the best Serie A teams of all time. Following the team's Serie A triumph, the squad narrowly missed out on several more league titles, finishing as runners-up for the next four consecutive years in 1957, 1958, 1959 and 1960. During his time with Fiorentina, Cervato also helped the club to reach the 1957 European Cup Final; despite a strong performance, Fiorentina were defeated 2–0 by Real Madrid.
