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.
