A large, tough, elegant, and physically strong player, Signorini is regarded as one of Italy’s best and last true sweepers; his talent, technical ability, and tactical intelligence as a central defender had a strong influence on Franco Baresi’s playing style. After having ended his playing career, Signorini started a managing career working for Pisa, and serving as joint caretaker manager during their 1997–98 Serie C2 campaign, However, he soon discovered he was suffering from amyotrophic lateral sclerosis, also known as Lou Gehrig’s disease, an illness that slowly forced immobility, paralyzing all his muscles. He died on 6 November 2002, in his Pisa home. In his honour, the #6 jersey, worn by Signorini during his time for the rossoblu club, was retired. Signorini was married to Antonella; together they had four children. On 17 May 2009, one of Signorini’s sons, Andrea, a footballer himself, made his Serie A debut with Genoa, thus continuing the legacy of his father and former rossoblu captain.
