Verza began playing professional football with Juventus but did not initially feature for the first team. After a spell with lower-level side L.R. Vicenza, he returned to Juventus at the age of 20, where he would make his Serie A debut against rivals Fiorentina on 26 February 1978. He later occasionally wore the number 10 shirt for the club, and scored several decisive goals during the 1980–81 Serie A season, including one against Napoli at the San Paolo Stadium, contributing to the club's league title victory that year.
