Juan Carlos "Toto" Lorenzo (; 27 October 1922 – 14 November 2001) was an Argentine football player and coach. He became an icon for Boca Juniors fans after he coached the club to its first two Copa Libertadores titles. Biography In his teens, Lorenzo played for Chacarita Juniors, and made his professional debut in 1940. He was transferred to Boca Juniors in 1945, and after two years he joined Italian side Sampdoria team, where he remained until 1952. His next clubs would be now-defunct French F.C. Nancy, and Atlético Madrid, Rayo Vallecano, and RCD Mallorca, where in 1958 he was coach and player. Then, he quit play but remained as coach. Lorenzo would be the coach that helped Mallorca to promote to Primera División for the first time in 1960. Influenced by Argentine-Italian Helenio Herrera and riding the wave of his success in Spain, Lorenzo coached Argentina's San Lorenzo in 1961, and coached the Argentina national team in the 1962 FIFA World Cup. Back to Europe, he coached Lazio to Italian first division, and coached AS Roma in 1964.

In 1973 Lorenzo went to Atlético Madrid, who went on to win the league title and lose the 1974 UEFA Champions League final to Bayern Munich. Back in Argentina, he coached recently promoted Unión de Santa Fe in 1975. The next year, he returned to Boca Juniors amid great pressure (rivals River Plate had just won back-to-back titles), and started one of the most successful periods in the history of the club. In his four-year tenure, Lorenzo and Boca took two local and three international titles, including the 1977 Intercontinental Cup (played in 1978).
