Juan Carlos Pérez López

Born in Santander, Cantabria, Juan Carlos started his professional career with local Racing de Santander after being promoted from its reserve side, Rayo Cantabria, in early 1966. He played two full seasons with the team, being relegated from Segunda División in 1968. In the following off-season, Juan Carlos signed with La Liga powerhouse FC Barcelona, making his debut in the competition on 24 November 1968 in a 1–0 home win against RCD Español. He only totalled 19 league appearances in his first two campaigns (four goals), mainly due to injuries. Subsequently, Juan Carlos became a first-team regular, also managing to be captain of a team which also included Johan Cruyff, Johan Neeskens and Carles Rexach. In 1973–74 he won the national championship – his second major trophy with the Catalans – contributing a career-best seven goals in 34 games, including the fourth in a 5–0 win at the Santiago Bernabéu Stadium over Real Madrid. In the 1975 summer, Juan Carlos returned to his previous club, now in the top division, playing a further three seasons. On 7 May 1978 he appeared in his last game, scoring in a 1–0 win against Sporting de Gijón which certified Racing's permanence in the competition.

Juan Carlos earned two caps for Spain, over a three-month period. His debut arrived on 24 November 1973 in a friendly with West Germany, playing 45 minutes in the 1–2 loss in Stuttgart.
