Early career Born in
Rome, capital of Italy, Sansovini started his professional career at
A.S. Roma. He was loaned to
Serie C1 club
Foggia in 1998–99 season. In mid-2000 he left for
Serie C2 club
Viareggio in a
co-ownership deal for a peppercorn fee of 1 million
Italian lire (about €516) along with
Andrea Giallombardo. He only scored twice in
2000–01 Serie C2. In June 2001 Roma gave up the remain 50% registration rights of both Giallombardo and Sansovini. In
2001–02 Serie C2, Sansovini found a way to score with 8 goals. In
2002–03 he changed to play for Serie C1 club
Sassari Torres. However, he only scored once in the first half of the season. In January 2003 he was loaned to fourth-tier team
Tivoli. Sansovini only played 9 times, but with an impressive 4 goals, nearly 0.44 goals per game. Sansovini returned to
Sardegna in
2003–04 Serie C1. However, he only played 615 minutes in the whole season with 2 goals. Sansovini transferred to
Pro Sesto of Italian fourth-tier in mid-2004. He netted 7 goals for the
2004–05 Serie C2 Group A champion. He also scored even more goals in
2005–06 Serie C1 (11 goals). Sansovini previously only had 3 Serie C1 goals in his accounts, with Torres. However Pro Sesto also had a second least goal scoring record and none of a players scored in the relegation "play-out". His striking partners, all failed to score. (
Marcos de Paula, 4 goals in half season;
Leandro Lázzaro, twice;
Claudio Salvi, once) However Pro Sesto re-admitted to Italian third-tier as numbers of club was expelled from that division due to different reasons. Despite remaining in Serie C1, Sansovini was sold to fellow third-tier club
Grosseto.
Grosseto Sansovini was signed by
Grosseto in mid-2006. He had a mix seasons with the Tuscany club. Sansovini did not have a place in
2006–07 Serie C1. He also failed to score in the first half of the season until he left for
Manfredonia. In late August 2007 he left for
Pescara. The team was newly relegated from
Serie B while Grosseto promoted to
2007–08 Serie B as third division group A winner. Once again Sansovini won a place in starting eleven and converted the chance to 16 goals. However
Franco Lerda did not trust any one of the rest of the strikers, while he used forwards such as
Luis Maria Alfageme (half-season),
Nico De Lucia (half-season) and
Nicola Falomi (half-season) as the partner of Sansovini in the formation. Despite the rotation of the squad, Pescara collected the most goals among the group and missed the promotion both by aggregate result against
Perugia and 1 point penalty. Sansovini's ability made Grosseto offering second chance to him. In his
maiden second division, Sansovini scored 15 goals, a goal shy than last season (16 goals). His goal scoring partner
Thomas Pichlmann also scored a considerable goals (12 goals) but not for
Alessandro Pellicori,
Ferdinando Sforzini (half-season) and
Marco Carparelli (half-season). Grosseto entered the promotion play-off, losing to
Livorno 4–3 in the first round/semi-finals. Eventually Livorno was the winner. Sansovini played both match with only one goal, while his partner Pichlmann (first match) and Pellicori (second match) failed to score. In
2009–10 Serie B, Sansovini was the starting forward along with Pichlmann. He failed to score and he was surprisingly sold to third division club Pescara on the last day of summer transfer window. On the same day Grosseto signed
Joelson as replacement and Alfageme few days earlier, in temporary deal and co-ownership deal for peppercorn respectively.
Return to Pescara On 31 August 2009, he returned to
Pescara in a definitive deal, in a four-year contract for €600,000 transfer fee, rejoining former Grosseto coach
Antonello Cuccureddu. Despite Sansovini was one of the starting forward with 26 starts, Sansovini only scored 4 times, only 1 more than his backup
Francesco Zizzari and
Mario Artistico (half-season). Another new signing
Massimo Ganci scored 8 goals with lesser start and
Samuele Olivi scored 4 goals as a defender. Both Sansovini and Ganci scored in the
promotion playoffs of the third division and Pescara promoted. Sansovini again found his shoes in
2010–11 Serie B with 11 goals. However Ganci and new signing
Cristian Bucchi and
Stefano Giacomelli all failed to score. Instead, winger
Massimo Bonanni was the second goalscorer of the team with 5 goals only. Pescara finished in the mid-table (13th /22teams) with 16th goal scored and 9th least goal conceded. Sansovini remained in the starting XI in
2011–12 Serie B. That season
Zdeněk Zeman used 4–3–3 formation. That season, Sansovini played 41 rounds with 16 goals, scoring his first ever hat-trick on 22 October 2011 in Pescara's 4-1 win against
Ascoli. Pescara also signed Juventus wonder-kid
Ciro Immobile and Napoli rising star
Lorenzo Insigne. The team had the most powerful goal scoring ability with 90 goals; Immobile was the league topscored with 28 goals, while Insigne had 18 goals and Sansovini was the third of the team. By the end of the season, Sansovini totalled 39 goals in a Pescara shirt, overtaking club legend
Bruno Nobili as Pescara's top-scorer of all times.
Spezia Despite failed to keep Immobile and Insigne whom both joined Pescara in temporary deals, as well as coach Zeman, Sansovini also left the club on 21 June 2012 to Serie B newcomer
Spezia for €150,000 fee in a two-year contract. On 25 July 2013, Sansovini added one more year to the contract. On 10 January 2014, he was signed by
