Alfio Basile
In 2007, Madero was designated again as physician for the national team under coach Alfio Basile, who was Madero's teammate in the national team in the late sixties . Madero endorsed FIFA's decision to prohibit the playing of international matches at a height of 2500 m (8200 ft) and above, citing medical concerns (notably, the increased incidence of respiratory alkalosis when playing in oxygen-poor environments).
