Pérez was used mainly as a backup during his six-year spell at the Santiago Bernabéu Stadium, but contributed to the conquest of two leagues and one Copa del Rey. His best individual season at the club was 1970–71 as he scored four goals in 20 games (19 starts), but Real came out empty in silverware, finishing the league in fourth position.
Also in the country, Pérez played one year in the top division for Real Zaragoza, then took his game to the Spanish lower leagues – appearing for three teams in as many seasons – before retiring in 1977 at the age of 30.
Pérez settled in Spain after his retirement, fathering two sons, Miguel and Alejandro, both of whom went on to represent several teams, almost always in the second division.[3][4]
