He was known for his powerful shots and creative play, his long-range efforts being dubbed Tikotazo. Over the course of 12 professional seasons he played mainly for Athletic Bilbao, appearing in 230 official games for his main club (nearly 200 in La Liga) and scoring 26 goals.
Born in Pamplona, Navarre, Tiko emerged through the ranks of hometown CA Osasuna, alternating between the A and B-sides for some time, with the former competing in the second division. His professional debut came on 10 May 1997, as he scored an injury time-winner at CD Badajoz (1–0).
In 1999–2000, Tiko signed with neighbours Athletic Bilbao, making his La Liga debut on 12 October 1999 in a 4–3 away win against Málaga CF. He would make 20 appearances all competitions comprised during the campaign, netting once.
From 2001 to 2006, Tiko was an undisputed starter in midfield for the Basque Country team, often scoring from free kicks and dictating Athletic's play. In his final two seasons he was severely hampered by injuries and the emergence of Carlos Gurpegui and Javi Martínez, playing in just seven league matches combined.
In August 2008, deemed surplus to requirements, Tiko joined second level club SD Eibar on a one-year loan deal. Upon his return to Bilbao following the former's relegation, he was immediately released, and retired from the game shortly after.
Tiko's younger brother, Francisco (nicknamed Txitxo), is also a footballer and a midfielder. He played exclusively in the lower leagues, also representing Osasuna B.
