Inter Milan
Youth
- 2009–10
Longo was a junior member of Inter's reserve team in the 2009–10 season, as a backup for Denis Alibec, Mattia Destro and Simone Dell'Agnello. On 28 January 2010, after being sparingly used by Inter, he left for Piacenza Calcio, along with Giuseppe Angarano and Luca Stocchi. In total, Longo only played 4 times in the reserve league that season.
- 2010–11
In the 2010–2011 season, despite Inter trimming their reserve squad (only composed only of U18 and U19 players plus 3 U20), Longo was unable to become a regular starter, with 11 appearances, (2 starts) and 2 goals. In January 2011 he moved to Genoa in a temporary deal with option to sign Longo in co-ownership deal, also as a replacement of outgoing reserve forward Gianmarco Zigoni. Longo scored 3 goals for Genoa and 2 goals for Inter in 2010–11 reserve league. He also appeared in the league's play-offs, losing to eventual champions Roma in the semifinals, forming a partnership with Richmond Boakye; his side was also eliminated by Inter in the quarter-finals of 2011 Torneo di Viareggio.

- 2011–12
In June 2011 Genoa signed Destro outright from Inter for €4.5M, as well as half of the registration rights of Longo for a peppercorn fee of €500 (also made Inter had to write-down €47,000 for the residual accounting value of his contract). [5] He returned to Inter in temporary deal on 1 July 2011, being again assigned to the reserves. Longo was a regular starter for the side, but was unable to be the topscorer, scoring eight goals times during the regular season (attacking midfielder Daniel Bessa eventually scored ten times).
Under Andrea Stramaccioni, Longo scored 5 goals in 2011–12 NextGen series as one of the team that won the tournament; his role also sightly changed after the arrival of Marko Livaja as new centre forward, in 4–2–3–1 (and later 4–3–3/4–3–2–1 formation under Daniele Bernazzani). He was also instrumental in the Primavera final stages, netting four goals in three matches (including a brace in the final against Lazio). [6]

On 2 September he made his debut abroad, scoring the first of a 2–3 away loss against Levante. [18] Longo scored his second goal on the 16th, in a 3–3 home draw against Athletic Bilbao, but was later sent off due to his celebration. [19]
