Following the good results during his stint with Atalanta, Avellino approached Bianchi to guide them for the 1983–84 season where they finished the season with an 11th place in the Serie A, and then the following season Bianchi moved to newly promoted Como where he managed to reach a mid-table position. The following season, Bianchi joined Maradona's Napoli, who won his first Scudetto in 1986–87. With Bianchi on the bench Napoli won the Coppa Italia in 1987, and the UEFA Cup in 1989.
