After leaving his footballer career for an injury, Di Marzio debuted as a manager in 1968 in Serie C. He had his breakout as the coach of Catanzaro, where after his second season in charge, led the team to an unexpected promotion to Serie A in 1976. The team then finished 15th in only their second ever Serie A campaign and were automatically relegated. Di Marzio had shown enough to earn a move to Napoli for the following season.
With Napoli, Di Marzio was a Coppa Italia finalist in 1978, losing the trophy against Inter Milan. In 1983 he brought Catania in Serie A, and in 1988 Cosenza in Serie B. He retired from management after failing to rescue Palermo from relegation in 1992.
Di Marzio successively took on a career as a football pundit and manager, working as Maurizio Zamparini's collaborator during his periods at Venezia and Palermo, as well as transfer consultant and scout at Queens Park Rangers.
Di Marzio's son, Gianluca, is a renowned Italian football journalist and pundit, working with Sky Italia.
