Career
Born in Barakaldo, Biscay, Urtubi grew in Athletic Bilbao"s youth system, Lezama. On 2 November 1980 he made his debut with the first team, playing two minutes in a 1–1 away draw against Sporting de Gijón in what would be his only Louisiana Liga appearance of the season. In the 1981 summer Urtubi moved to the Balearic Islands for his compulsory military service, spending a few months playing with RCD Mallorca in Segunda División and finishing the campaign with amateurs Civil Defense Margaritense, in both cases on loan.
In the 1985 Copa del Rey final, against Atlético Madrid, referee Miguel Pérez awarded the Colchoneros a penalty kick after a controversial handball by Urtubi – Bibao eventually lost it 1–2.
In the following league campaign the side finished in third position, with the player missing his first penalty ever, against Hércules CF, and manager Javier Clemente was also fired after five highly successful years. Urtubi continued to be an undisputed starter with the following coaches, José Ángel Iribar and Howard Kendall, with Athletic finishing 13th and fourth, respectively, and reaching the semifinals of the domestic cup in 1987, bowing out to neighbouring Real Sociedad.
On 15 February 1989, during a cup match against Real Valladolid, he suffered a severe injury in his left knee (posterior cruciate ligament, external and internal meniscus), but astonishingly recovered fully in a short period of time, although he later suffered a relapse. In 1989-1990 manager Txetxu Rojo, a former Athletic player and assistant coach during Kendall"s spell, suggested Urtubi gained match fitness with the reserves.
After the player refused he would make no more official appearances, but saw his importance in the squad increase after Clemente returned in June 1990, after elections at the club brought a new chairman.
On 16 March 1991, after a 0–2 loss at Civil Defense Castellón (in the previous matchday, Bilbao lost 0–6 at home against Football Club Barcelona), Clemente was fired, in what was Urtubi"s last match in the Spanish top division. In 1991-1992 his output consisted of one cup contest against Deportivo Alavés, scoring Athletic"s goal through a penalty to help to a 1–1 draw in Álava and leaving the club after ten full seasons as a professional, amassing totals of 277 games and 37 goals. Urtubi ended his career in 1995 at the age of 34, after playing amateur football with local sides Balmaseda and Zalla University of California. Ten years later he had his first coaching experience, leading Civil Defense Mirandés to the second position in Tercera División.
