Under new coach Cesare Prandelli, Parma played an offensive 4–3–3 formation, in which new offensive signings Adrian Mutu and Adriano starred. Both made up for the departure of Marco Di Vaio to Juventus. Mutu scored 18 goals from the left wing, and Parma accepted a multimillion-pound offer from Chelsea in the summer, which meant the Romanian international only spent a year at the club. Also impressing were goalkeeper Sébastien Frey and young centre-halves Matteo Ferrari and Daniele Bonera, who proved to be acceptable replacements for departed captain Fabio Cannavaro, who had joined Inter in late August 2002.
Document 2: Antonio Cassano: Antonio Cassano (] ; born 12 July 1982) is an Italian former professional footballer who played as a forward.

Nicknamed "Il Gioiello di Bari Vecchia" ("the jewel of Old Bari"), and "Fantantonio" ("fantastic Antonio"), he was known for his short temper as much as his skill and ability on the pitch, which led to the coining of the neologism "Cassanata" by his former Roma and Real Madrid coach, Fabio Capello, in November 2002, due to their disputes over his actions. The word is regularly used by Italian journalists as a euphemism for any behavior incompatible with team spirit in football.
