Jonathan Calleri is a Brazilian football manager who has made significant contributions to the sport. He was born in Rio de Janeiro, Brazil on December 12, 1977 and began his career playing for several clubs before becoming a professional player. After retiring from playing, he moved to Europe and worked as a coach in Germany.
Calleri's first managerial job came at Deportivo S.L., where he was responsible for leading the team to the UEFA Cup Winners' Cup semi-finals in 2005. His work there earned him praise from fans and players alike, but it was not until he took over Atletico Mineiro that he truly gained recognition.
At Atletico, Calleri introduced a wing defense system that became one of the most effective in South America. This system allowed the team to create space for their attacking players to move freely and create opportunities for goals. One of the key aspects of this system was the use of a high center of midfield, which allowed the team to play with a more balanced attack.
One of Calleri's greatest achievements was winning the Copa Libertadores in 2008, when the team defeated Real Madrid and won the tournament. It was a historic moment for the club and its fans, and it cemented Calleri's reputation as one of the best managers in South American football history.
In addition to his managerial career, Calleri has also been involved in coaching youth teams and developing young talent. He has helped to develop players like Lucas Hernandez and Oscar Mendy, both of whom have gone on to become major stars in their respective countries.
Despite his success as a manager, Calleri remains humble and grateful for the support he received throughout his career. He credits his success to his passion for the game and his unwavering commitment to his craft. Despite facing criticism from some quarters, Calleri remains committed to helping to build a stronger and more competitive South American football league.
