Aimo Stefano Diana (born 2 January 1978 in Brescia) is an retired Italian footballer who last played for Trento Calcio 1921. A player of wide range, he can appear as a midfielder or a defender, always on the right flank.
A product of Brescia Calcio's youth system, Diana made his debuts for the first team in the second division in 1997, and played his first Serie A game on 31 August of the same year, against F.C. Internazionale Milano. He played one season with Hellas Verona F.C. in a co-ownership deal, helping the side to a final 9th position in the top level, and left for Parma A.C. in 2001.
Diana was used irregularly by the Emilia-Romagna side, winning the Italian Cup in his first season, but hardly featuring at all in 2002–03. In January 2003 he moved on loan to Reggina Calcio along with Emiliano Bonazzoli, posteriorly signing for U.C. Sampdoria at the end of the season. A key member from the start for the Genovese, he helped the team qualify for the UEFA Cup in his second year, scoring five goals in 32 matches; in early May 2005, he scored the game's only at Juventus F.C. and, the following week, also found the net, in a 3–0 home success against ACF Fiorentina.
In the 2006 summer, Diana signed for U.S. Città di Palermo for €5 million, with Sampdoria also selling Marco Pisano to the same club for €4 million and receiving Massimo Bonanni (50% for €2million), Pietro Accardi (€2 million) and Christian Terlizzi (50% for €1.5 million). He was regularly used in one 1/2 seasons and scored two goals, including the equalizer in a 2–1 home win by the Rosanero against A.C. Milan on 26 September 2007. On 30 January of the following year he was sold to Torino F.C. in a permanent move, for €1.2 million.
In early January 2010, Ultras of Torino attacked club players during David Di Michele's birthday party. After the incident, Riccardo Colombo, Diana, Di Michele, Massimo Loviso, Marco Pisano, Francesco Pratali and Paolo Zanetti were transferred to other clubs, with only Rolando Bianchi, Angelo Ogbonna and Matteo Rubin remaining.
Diana joined AC Bellinzona in Switzerland on loan in early February 2010, making his Super League debut on the 21st in a 1–2 away loss against FC Luzern, eventually contributing solidly (15 matches, 14 starts) as the club narrowly retained its division status.
Subsequently, 32-year old Diana returned to Torino. On 4 January 2011 he mutually terminated his contract, re-signing for Bellinzona (on a permanent basis) the following day.
A regular for the Azzurri under Marcello Lippi, an injury prevented him from being picked to the squad at the 2006 FIFA World Cup in Germany. On 2 June 2007, in his last appearance, Diana assisted on Filippo Inzaghi's second goal against the Faroe Islands, in a 2–1 away win for the UEFA Euro 2008 qualifiers.
