Province of Toledo
Born in Carriches, Province of Toledo, Castilla-La Mancha, Leal finished his youth career with Atlético Madrid. After alternating between the first team and the amateur reserves to start with, he was loaned to fellow La Liga team Sporting de Gijón, returning to the Vicente Calderón Stadium late into the 1973–74 season to play the Copa del Rey as the foreign players were not eligible for the tournament. He started playing football as a forward, but manager and former teammate Luis Aragonés reconverted him in a midfielder.
