[3] Robledo started his footballing career at Huddersfield Town, playing as a part-time amateur while he earned his money coal mining, though he never managed to break into the first team.

Newcastle came out of the match 2–1 winners, with Robledo's goal separating the sides, helping to quickly make him a fan favourite.

The goal scored by Robledo was drawn by a young John Lennon, who included it in the artwork of his album Walls and Bridges in 1974.

He made his debut in the opening group game against England (one of his opponents reputedly warned him after he'd hit the post "Steady, George, you're not playing for Newcastle now, you know")[8] and scored in Chile's 5–2 victory over the United States.

He finally retired from football in 1961 and took charge of the sports program in St Peter's school, Viña del Mar, where he remained leading a quiet life until his death of a heart attack on 1 April 1989, just before his 63rd birthday.

[9] His brother Ted had died nearly 20 years earlier, having fallen from an oil tanker into the sea off the coast of Dubai in December 1970.
