José María Maguregui
Born in Ugao-Miraballes, Biscay, Maguregui made his professional debuts in 1952 at the age of 18, with Basque Country giants Athletic Bilbao. After a poor first season in La Liga – 12 games, no goals – he became a very important first-team unit, helping them to the 1956 national championship and three Copa del Rey trophies in four years.
