#2 Carlos Bilardo
"I silenced many critics who had said I was mad for changing the national team's system of play to 3-5-2 in 1984 - an almost revolutionary formula at the time," he said. When he was appointed Argentina coach in 1982. Bilardo's style was the antithesis to his successor Cesar Menotti, whose Argentina side's swashbuckling style earned them the world title in 1978.
To Bilardo, winning was all that mattered and it didn't matter how it was achieved, ideas honed as a player in an Estudiantes side whose outlook on fair play was slightly more flexible than others. However, the manager guided Argentina to two consecutive World Cup final appearances in 86 and 90.
Argentina may never have had one of its most influential coaches had he maintained his academic interests.
"I studied medicine and worked as a gynecologist for five or six years.
"Medicine has always fascinated me. I played football while I was studying and working in a hospital. One day I was faced with a decision because I couldn't be here, there and everywhere. I plumped for football."
