Mantovani started his career at Torino Calcio. He was the member of Allievi Nazionali Under-17 team in 2000–01 season. In 2002–03 season, he occasionally received first team call-up, and made his debut on 19 January 2003 against Como, which he replaced Gianluca Comotto at half-time. The match ended in 0–0 draw.
After Torino relegated in 2003, he was loaned to Serie B side Triestina. In 2004–05 season, Mantovani returned to Turin and played as one of the regular starter, he was awarded no.4 shirt. The team won promotion playoffs but then went bankrupt. FIGC allowed a new successor team admitted in 2006–07 Serie B but the players were also allowed to leave on free transfer.
In August 2005, he was signed by Serie A side Chievo along with team-mate Giovanni Marchese and on 30 August sold to Torino's rival Juventus in co-ownership for a nominal fees of €1,000. He was immediately loaned back to Chievo and played 4 league matches.
Partially due to 2006 Italian football scandal, Juventus terminated all ongoing co-ownership deal in June 2006, and Mantovani was sold back to Chievo for about €301,000. He played 3 out of 4 European matches of Chievo, which exited in both UEFA Champions League 3rd qualifying round, and UEFA Cup first round.
Mantovani played 15 league start in 2006–07 season. Chievo was slipped from 4th (post-trail) or 7th (pre-trail) in 2005–06 to 18th that season, and Mantovani followed the team relegated to Serie B. At Serie B, Mantovani became an absolute starter, started 36 out of 42 matches, missed round 16 and round 22 due to suspension, 1 match as substitute and rested on last round (round 42).
In June 2008, he signed a new 4-year contract with club. Since returned to Serie A, he continued to play as a regular and helped the team survived in relegation battle. In 2009–10 season, he played as left-back or one of the 3 central defenders in 352 formation and helped the team remained in Serie A. He either ahead Bojan Jokić as left back or partnered with Jokić on the left flank: Jokić as wingback and Mantovani as left central defender.
On 6 July 2011, after weeks of speculation surrounding his future, Mantovani agreed a four-year deal with Palermo with €3.5 million transfer fee, thus re-joining his former Chievo head coach Stefano Pioli to Sicily. He debuted with the rosanero on 28 July against Thun in Europa League.
