 In 1993, he played as the starting keeper for Torino Calcio for a single season, reaching the semi-finals of the Coppa Italia, and the quarter-finals of the Cup Winners' Cup, despite a disappointing mid-table finish.He finished his stint in the top division at the end of the 1994–95 season, after being named backup goalkeeper behind Luca Bucci at AC Parma, who won the UEFA Cup that season, and reached the Coppa Italia final, also placing third in Serie A.

Galli retired in 1996 at the age of 38 after a brief stint with A.S. Lucchese-Libertas of Serie B.

Galli took part in Italy's victorious 1982 FIFA World Cup expedition, without playing a single match however, as he served as backup to Dino Zoff, alongside Bordon.The same had already happened in the UEFA Euro 1980 tournament, where Italy finished in fourth place on home soil, after reaching the semi-final.
