Born in Imola, Province of Bologna, Mannini started playing professionally with Calcio Como in Serie B, appearing in 36 games in his second season as the Lombardy team promoted to Serie A. In the following off-season he signed with fellow top-divisioner U.C. Sampdoria, where he remained for the following 15 years almost always as an undisputed starter; in the late 80's/early 90's he was part of a defensive sector which also included Gianluca Pagliuca, Luca Pellegrini, Pietro Vierchowod and Amedeo Carboni, with Roberto Mancini and Gianluca Vialli providing the goals.
During his spell with Samp, Mannini won four Coppa Italia and the 1991 national championship, scoring a crucial goal in the latter competition on 19 May in a 3–0 home win against U.S. Lecce. He also appeared in two UEFA finals in the 90's, winning the UEFA Cup Winners' Cup against R.S.C. Anderlecht and losing the European Cup against FC Barcelona, the latter match played at Wembley.
In the 1999 summer, following Sampdoria's top level relegation, 37-year-old Mannini – who appeared in 510 official games for the club, netting eight times – left Genoa and signed for Nottingham Forest in the Football League Championship, reuniting at the English side with former Sampdoria teammate (and manager) David Platt. He made his official debut on 7 August 1999 in a 1–3 away loss against Ipswich Town, leaving in the following transfer window and closing out his career after a few months with his first team, amateurs Imolese Calcio 1919.
