In January 2003, he moved on loan to Reggina along with Emiliano Bonazzoli, posteriorly signing for U.C. Sampdoria at the end of the campaign. 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 FC and, the following week, also found the net, in a 3–0 home success against ACF Fiorentina.

After impressing Sampdoria, Diana received his first call-up to the Italy national team, making his debut in a friendly match with Spain on 28 April 2004. 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 qualifying.

After retiring, Diana became a youth coach at Feralpisalò, being successively promoted to head coach in November 2015. He completed the season in eighth place in the 2015–16 Lega Pro, not being confirmed for the following year. In August 2016, he was hired new head coach of Pavia, but resigned shortly thereafter, following the club's exclusion from Serie D due to financial issues. In February 2017, he was signed by Lega Pro club Melfi, failing to escape relegation by the end of the season. He returned into management in December 2017 as the new boss of Sicilian Serie C club Sicula Leonzio.

He guided Renate for three full seasons, the last of which ended with Renate topping the league for a long time until losing out to more renowned teams such as Como and Alessandria, and then losing to second-placed Girone B club Padova in the promotion playoffs. Following that, Diana agreed to leave Renate and accepted to join recently-relegated Serie C club Reggiana on a one-year deal, with an option of further extension in case of promotion to Serie B. After guiding Reggiana to win promotion to Serie B as 2022–23 Serie C Group B champions, Diana left the Emilian club by the end of the season.
