Quincoces
Juan Carlos Díaz Quincoces (26 January 1933 – 28 November 2002), known as just Quincoces, was a Spanish footballer who played as a defender. He made eight appearances for the Spain national team from 1957 to 1959. His uncle Jacinto Quincoces was also a professional footballer and a Spanish international as well as a prominent coach, with Juan Carlos usually referred to by his maternal surname - and as 'Quincoces II' - in recognition of his famous relative (conventionally the paternal surname Díaz would have been used). They worked together at Valencia as coach and player in two spells. References
