Robledo was born in
Iquique, Chile to a Chilean father and an English mother. He emigrated with his family to
Wath-on-Dearne, Yorkshire in 1932, at the age of four, due to the political instability in Chile at the time. The family lived at Barnsley Rd,
West Melton, in the same house where the Anglo-French biographer
David Bret was later raised. Robledo started his footballing career at
Barnsley with his brother
George.
First Division Newcastle United signed him on 27 January 1949. Newcastle were only interested in signing his brother, but neither of the Robledo brothers would move without the other. Their appearance together in the
1952 FA Cup Final was the first time more than one foreign player had appeared in a cup final team. The majority of Robledo's appearances for the club came in the 1951–52 season. He played for Newcastle until the end of the 1952–53 season, when he was sold to
Colo-Colo. He returned to England in 1957 for a brief spell with
Notts County, making two appearances. At international level, he earned nine caps for
Chile national team between 1954 and 1955. After retiring from football, he served on an oil tanker where he died in mysterious circumstances in December 1970, at the age of 42. It was rumoured that he was thrown off the tanker and drowned. His body has never been found. His brother George outlived him by nearly two decades, dying in April 1989 just before his 63rd birthday. ==Honours==
