[1] Due to Virgilio Maroso's injury, Operto found room in the team in the first matches of the 1948–49 championship.

He debuted in Turin's internal race against Roma at the Stadio Filadelfia on 3 October 1948.

At the end of the season he collected 11 appearances;[2] Maroso's return to the club for a long time stopped him from playing with more continuity.
