Internazionale Born in
Buenos Aires to Italian parents, Dellafiore started his professional career with
Internazionale. Dellafiore had played for Inter since the 1999–2000 season and was promoted to the
Primavera team, during the 2002–03 season. Dellafiore managed seven appearances in his first season with the
rosanero. He was then loaned to
Torino for €100,000 (with option to purchase), where he had the opportunity to play more regularly, before being called back to Sicily in June 2008 (which Palermo paid Torino €400,000 to counter the buy option). but on 14 January 2009 turned back to
Torino F.C. on loan for €400,000. After 6 months with
Torino, Torino president
Urbano Cairo announced that Dellafiore will play for Palermo for 2009–2010 after the team was relegated.
Parma (loan) On 3 July 2009,
Parma signed Dellafiore on loan from
Palermo, for €250,000, with an option to sign half of the rights for €1.75 million. After the end of the season, Dellafiore returned to Sicily, but was later loaned out again to Parma on 20 August 2010, for free with an option to sign half of the rights for €400,000. He was sub-loaned to Cesena on 7 January 2011, for €200,000.
Parma & Novara In August 2011, he was permanently transferred to
Parma F.C., for free. In the same month, he moved to Serie A newcomers
Novara Calcio for a peppercorn of €500, in
co-ownership deal. In May 2012, Dellafiore returned to Internazionale for its Indonesia friendly tour on a 1-month loan. In June 2012 Dellafiore returned to Parma for €250,000, which also cost Parma an additional €200,000 as other fee.
Siena In late June to 1 July 2012, Dellafiore was involved in 8-men swap with
Siena, which saw
Coppola, Dellafiore,
Doumbia and
Galuppo went to Siena, with
Brandão,
Pacini,
Rossi and
Iacobucci went to Parma. None of the new players actually played for Parma, only able to bring financial success to both clubs. Dellafiore himself failed to play regularly for Siena in Serie A, only able to play twice before leaving for his first Serie B club
Padova in temporary deal. At the end of the season, Siena was relegated, and Dellafiore followed the club for the new season. Dellafiore made his best season with Siena in
2013–14 Serie B, in terms of total appearances of 35 Serie B games. At the end of the season, the co-ownership between Siena and Parma was renewed again, and Siena was expelled from Serie B due to financial difficulties. Dellafiore became a free agent soon after.
Latina On 23 July 2014, Dellafiore was signed by Serie B club
Latina along with former Siena team-mate
Ângelo,
Farelli and
Valiani. He left the club in June 2017 after the club was relegated to Serie D for bankruptcy.
Perugia On 12 January 2018, he was signed by Serie B club
Perugia after six months of inactivity.
Paganese On 5 February 2019, after sitting out another half-year without a club, he signed with
Serie C club
Paganese. He left the club by the end of the season. In August 2019, he accepted to return to
Palermo on trial, after the club was refounded and forced to restart from
Serie D. He was, however, not offered a contract by the end of the pre-season training camp.
Mantova Dellafiore ended up joining
Serie D club
Mantova on 6 December 2019, signing a deal until the end of the season. ==International career==
