As a young man he was a player in Tuscan amateur teams, including the Forte dei Marmi.
His career as a manager in football starts in the 1994/95 season in Fiorentina, and in the following year he won his fifth Italian Cup.
In 2002 he spent two seasons at Lazio, who won the Italian Cup in 2004 under the guidance of Roberto Mancini.
His adventure in Sardinian land, however, lasts very little, Cellino is in fact was determined to manage the football market in first person and Cinquini, while entering into good negotiations, was subject to the decisions of the President, who, after a disastrous start of the championship decides to get rid of him.
In June 2007, some voices saw him close to taking Bettega's place at Juventus after a period of inactivity, in which, however, as an external observer, he gave a hand to La Spezia on the verge of bankruptcy,[3] and on 18 July 2008 he signed with Pisa as head in technical area.
