He is best remembered for being the coach of Napoli from 1985 to 1989, a team consisting of great players such as Diego Maradona and Careca, which won its first of two Serie A titles in the 1986–87 season.

After four successful seasons with Napoli, Bianchi moved to Roma, where he once again won the Coppa Italia in 1991, and also managed to reach the UEFA Cup final, where the club finished as runners up to Inter.

The next year Bianchi was appointed as a technical director, guiding Marcello Lippi after the team lost several important players such as Gianfranco Zola, Careca and Giovanni Galli due to financial difficulties.

Seven years later, Bianchi was called to save relegation troubled Fiorentina in 2002[3] without success both as a coach and as chairman of club, succeeding the outgoing Ugo Poggi until the end of the season.

Bianchi was a traditional and defensive–minded manager, who was known for his tactical prowess and effective counter-attacking style, with his teams often sitting and cancelling out their opponents only to hit them on the attack after winning back the ball.
