Massimo Bonini

Bonini began his career at Juvenes Dogana in 1973 but failed to make a league appearance during his 4 years at the club. After leaving Juvenes Dogana in 1977, he moved on to join Bellaria, going on to make 33 appearances scoring 1 goal. After leaving Bellaria in 1978, he moved on to join Forli, going on to make 23 appearances, scoring 1 goal. After leaving Forli in 1979, he moved to Cesena, appearing 60 times and scoring 5 goals. After leaving Cesena in 1981, Bonini played for Juventus between 1981 and 1988, in which he played 296 matches and scored 6 goals. He won three Serie A titles, the 1982–83 Coppa Italia , the 1983–84 European Cup Winners' Cup, the 1984–85 European Cup, the 1984 European Super Cup, and the 1985 Intercontinental Cup. He is the only Sammarinese footballer to have won an official international title. For his performances, he was awarded the Bravo Award in 1983, as the best under-23 player in European Competitions. After leaving Juventus in 1988, he moved to Bologna going on to make 112 appearances and scoring 5 goals. Bonini retired in 1993.

Since the San Marino Football Federation was not officially recognised by the UEFA until 1990, players from San Marino were assimilated to Italian players. For this reason, Bonini was entitled to play for the Italian Football Federation and actually played for the Italian Under-21 football team. Since he always refused to give up the citizenship of San Marino, he had to wait until 1990 in order to play for San Marino's first team, winning 19 full caps since then. He played his first match for San Marino against Switzerland on 14 November 1990.

After his retirement, Bonini briefly served as the head coach of the San Marino national football team, from 2 June 1996 to 10 September 1997.

Bonini was a hardworking, energetic and versatile box-to-box midfielder, who was frequently deployed as a central midfielder or as a defensive midfielder during his time at Juventus. Although this position did not provide him with the freedom to contribute offensively or creatively that he had possessed in his early career, he excelled in his new role as a ball winner, and at breaking down opposition plays due to his tactical intelligence, workrate, and positional sense, supporting his more creative teammates defensively, such as Michel Platini (the playmaker), alongside Marco Tardelli (a mezzala). He was known in particular for his pace and stamina, which earned him the nickname "Platini's lungs" due to his successful partnership in midfield with the Frenchman.
