Even though he was born in Galicia, José Diego and his family moved to the Basque Country as he was still an infant, settling in Eibar. He started playing football for local Sociedad Deportiva, going on to appear in three Tercera División seasons with the team.
In the 1974 summer, José Diego was signed by neighbouring Real Sociedad, making his La Liga debut on 7 September (two months before his 20th birthday) in a 3–2 home win against FC Barcelona and finishing his first year with eight games. From the following campaign onwards he became a very important unit for the Txuriurdin, going on to contribute with 96 matches and seven goals in three seasons combined as they won the national championship in 1981 and 1982, adding the second position in 1980.
After only two appearances in 1984–85, José Diego retired from football at the age of 30. He played in 349 official games for his main club, scoring 23 goals.
José Diego earned one cap for the Spanish national team, playing the second half of a 0–2 friendly loss with England at the Camp Nou, on 26 March 1980. He was picked for the squad that participated in that year's UEFA European Championship, being an unused squad member.
