Bolo

Born in Bilbao, Biscay, Bolo was a product of Lezama, Athletic Bilbao's youth structure. He first appeared with the first team on 20 February 1994 in a 1–0 away defeat against Real Zaragoza, in what would be his sole La Liga appearance of the season. After a four-year stint with the Basques (with loans to Osasuna and Hércules in the Segunda División included), Bolo went on to play for Rayo Vallecano, where he had his most steady period, appearing in the UEFA Cup in the 2000–01 campaign and being joint-top scorer (alongside Dimitar Berbatov) with seven goals to help his team reach the semi-finals; at times, he formed part of a forward line alongside two Bosnian internationals with very similar names: 'Baljić, Bolić and Bolo'. He suffered consecutive relegations in his last two years, at Gimnàstic de Tarragona and Numancia. In August 2008, Bolo was released by Numancia as the Soria team returned to the top flight, and returned to the Basque region, signing with Segunda División B side Barakaldo. After only one season, he retired from football at the age of 35, becoming his last club's general manager.

Bolo was never capped by Spain at any level, but represented the Basque Country's non-FIFA team. On 27 December 2003, he scored both goals in a 2–1 win over Uruguay at his hometown's San Mamés Stadium.

Bolo was appointed manager of Arenas de Getxo on 18 March 2014, achieving promotion in his first full season. On 31 May 2018, he was named at the helm of Ponferradina also in the third tier, again promoting in his debut campaign. On 27 May 2022, Bolo announced that he would leave the club at the end of the season. On 15 June, he took over fellow second-division side Real Oviedo, being dismissed on 16 October. Bolo replaced the departing Julián Calero at Burgos on 31 May 2023. On 28 October of the following year, he was sacked after a poor start to the campaign. On 12 November 2025, Bolo was appointed at fellow second-tier Huesca. He was relieved of his duties in March 2026, having collected just 16 points from 17 matches and with the team in the relegation zone.

Bolo's son, Adrián (born in Madrid in 2001 while his father was with Rayo), is also a footballer. A central defender, he also came through at Athletic Bilbao. Bolo's father Juan Antonio was also involved in the sport as a forward. He notably played for Tercera División club Santurtzi, and died on 19 December 2022 at age 79.
