Aristide Guarneri (Italian pronunciation: [a'ristide gwar'n??ri]; born 7 March 1938) is an Italian former footballer who played as a defender.
Initially a fullback at the beginning of his career, he was later usually deployed as a centre-back, where he excelled due to his anticipation, tackling, marking, and ability to read the game.
Guarneri was known as a "gentleman of the game", as he never received a red-card throughout his career, despite being a tenacious defender.
