Born in Mungia, Basque Country, Yosu played professionally during roughly one decade, appearing in 122 matches in La Liga where he represented Racing de Santander, Valencia CF, Athletic Bilbao and Pontevedra CF, retiring in 1972 at only 31 after spells with CF Calvo Sotelo in Segunda División and lowly Gimnástica de Torrelavega from Tercera División.
In his beginnings, Yosu was also loaned by Racing to Deportivo Rayo Cantabria, at the time acting as a feeder team. Whilst with the Che he was used rarely in the league – also being loaned to Santander – but scored twice against FC Barcelona in the 1961–62 Inter-Cities Fairs Cup final, a 6–2 home win (7–3 on aggregate).
Immediately after retiring, Yosu began coaching at his last team Gimnástica, even though he did not possess the obligatory licence. Afterwards he returned to main club Racing, starting with its youth teams.
From 1977 to 1979, Yosu served as head manager for Santander, but would work with the club in several other capacities, from match delegate to director of football. Additionally, in no fewer than five occasions, as an interim manager in the 90's/2000's, he successfully led the side away from relegation zone, always in the top level.
In March 2007, Yosu was honoured by the Government of Cantabria for his contribution to football in the area. He retired from the football world for good in January 2009, after leaving his post as Racing's director of football.
