Now he works as manager for Italy national cycling team In 1982 he made his professional debut with Termolan-Galli. In 1986 he moved to Carrera, where he supported figures such as Claudio Chiappucci, Roberto Visentini and Stephen Roche. Cassani later raced for Gewiss-Bianchi, Ariostea, Great Britain-MG and Saeco.
He retired in 1996 after being hit by a car in training.
After retiring from cycling, he became a commentator at Italian public broadcaster Radiotelevisione Italiana. In 2007, he was involved in the withdrawal of Michael Rasmussen from the Tour de France. Cassani claimed to have seen Rasmussen in the Dolomites mountains in Italy, while Rasmussen and Rasmussen"s in-laws claimed that he was in Mexico at that time.
His comment, coupled with other issues concerning Rasmussen, led to his expulsion from the Rabobank team The claim was first made a week or so before the controversy exploded — as a routine comment during the Rai Tre afternoon coverage of the Tour.
lieutenant took the form of a compliment to the athletic dedication of Rasmussen who has apparently been returning from eight hours of mountain training, so Cassani appears to have had no axe to grind against Rasmussen.
In 2010 Cassani claimed Swiss cyclist Fabian Cancellara used a motorised bike in some of his victories. Cassani has also collaborated with Ivan Zazzaroni and Pier Bergonzi to write a biography of Marco Pantani, Pantani. Un eroe tragico (Pantani, a tragic hero).
