Early career Moretti started his career with local club
Lodigiani, and in 1998 transferred to
Fiorentina. He made his Serie A debut in March 2001, and was a member of the team that won the 2001
Coppa Italia. In the 2001–02 season, he played in 27 matches. Right before the Fiorentina
bankruptcy, Moretti moved to
Juventus in June 2002 for a fee of €2.6 million, In 2003,
Parma signed Moretti for €1.8 million (part of
Stephen Appiah's €2 million loan), loaning him to Serie A team
Bologna. In 2004, with Parma facing financial problems and
Claudio Ranieri becoming head coach of
Valencia, the left defender was traded to Valencia.
Valencia In the summer of 2004 he was transferred outright to Spanish club Valencia, who had already purchased fellow Italians
Bernardo Corradi,
Marco Di Vaio and
Stefano Fiore. On 27 August, while remaining on the bench, he was part of the team that won the
UEFA Super Cup, beating Porto 2–1.
Claudio Ranieri would use Moretti predominantly at left-back, and, despite a difficult start due to competition with
Fábio Aurélio and compatriot
Amedeo Carboni, would soon earn the starting spot. He scored his first goal for Valencia on 28 November 2004 in the
Primera División in a 2–0 home win against
Mallorca. In the
Champions League he played 4 games against
Inter Milan,
Werder Bremen and
Anderlecht, with 29 appearances during the season. The following season, he was a starter, making 33 appearances and a decisive contribution to the achievement of a third-place finish. At the beginning of the following season, on 6 November 2006, in the match against
Espanyol, Moretti was seriously injured, damaging his lateral ligament of the knee, forcing him to the sidelines for more than three months. Despite the injury, the season remained one of the most important on a personal level and as a team, which reached the quarter-finals of the Champions League, defeated only by
Chelsea. Moretti ended the year with 34 total appearances. The 2007–08 season was not as positive, which concluded with Valencia tenth. Moretti remained a protagonist of the side, leading to Valencia's victory on 16 April 2008 in the
2008 Copa del Rey final, playing all the matches from the initial stage to the final. The following season, he was still a starter in the Spanish side, which reached the first knockout round of the
UEFA Cup, which concludes the year sixth place in the Primera División. Moretti disputed 32 games.
Genoa After 172 appearances and 4 goals with the Spanish club, he returned to Italy to play for
Genoa, engaged in the
Europa League. The transfer fee was €3.5 million, according to Genoa. He made his debut for Genoa on 23 August 2009, a 3–2 victory at home against
Roma. A week later he scored his first goal in red and blue colours against
Atalanta. His first season with the
Grifoni finished with 37 appearances and 1 goal in total. The following year, he only made 18 appearances under
Gian Piero Gasperini, while the team finished the season in tenth place. The 2011–12 season is even more difficult for the team, and despite 27 appearances and a goal (against Inter Milan), Genoa finished in fourth last position. He was confirmed part of the Genoa defence for the 2012–13 season, contributing 33 total appearances. On 5 May 2013, he celebrated his hundredth appearances in
Serie A with the shirt of Genoa, on the occasion of a match ending 4–1 against
Pescara.
Torino After being close to a renewal with Genoa, on 11 July 2013 he was signed by
Torino on a free transfer, on a two-year contract. He made his competitive debut for the
Granata on 17 August, in
Coppa Italia against
Pescara. He scored his first official goal for Torino on 24 December in a 4–1 win against
Catania. At the end of the season he extended his contract until 2016. On 25 January 2015, he scored a goal in the 94th minute in which Torino defeated
Inter Milan at
San Siro after 27 years. It was his second goal for Torino. On 30 August, he scored his first goal of the
2015–16 season, the equaliser in a 3–1 home win against
Fiorentina. On 25 November, his contract was renewed until 2017. On 2 April 2017, he scored his first goal of the
2016–17 season in a 2–2 home draw against
Udinese. On 5 April, his contract was renewed until 2018. On 26 May 2019, he made his last appearance for Torino and of his football career, coming on as a substitute for
Armando Izzo, and helped Torino beat
Lazio 3–1 at home, after which he retired from professional football; in total, he collected over 600 career appearances at club level ==International career==
