Marcelo Bielsa is managing a country at a World Cup for the third time in his career. The 70-year-old is one of the most respected coaches in the game, earning his reputation through obsessive dedication to preparation. He has spent his career studying every detail, from player clips to opposition teams.
More than two decades ago, Bielsa took 2,000 video tapes to Japan for the 2002 World Cup, covering everything from his players' club performances to their World Cup opponents. Modern technology has made this process easier, but Bielsa will still have a vast library of clips for the 2026 World Cup.
Born in Rosario, Argentina, Bielsa comes from a family of analytical thinkers. His brother worked in politics and his sister is a renowned architect, professions that require careful consideration. Bielsa possessed this gift from childhood, but he was drawn to football, particularly tactics. Every day, he would ask his mother to buy football magazines and newspapers, spending hours reading about teams and managers.
Bielsa was a capable but limited player, lacking pace as a defender. He came through the youth system at Newell's Old Boys before moving to the lower leagues, where he decided to focus on coaching at 25. His post-playing career started with the Buenos Aires university team, and after two years, he secured a position at Newell's as reserve team coach.
Bielsa's frustration as a player influenced his coaching philosophy, focusing on getting the most out of each player's ability. His training sessions were intense, with a focus on repetition, drilling processes into players' minds. Bielsa was appointed Newell's manager in 1990, bringing instant success with a championship win.
A spell in Mexico followed before Bielsa returned to Argentina in 1997 to manage Velez Sarsfield. He was labelled 'loco' for fielding two teenage centre-backs, but he had the last laugh with a league title win. Bielsa briefly managed Spanish side Espanyol before becoming Argentina boss in 1998, his first international post. Bielsa has said his 'El Loco' nickname predates his time at Velez Sarsfield.
