Landáburu was born in Guardo, Province of Palencia. He made his professional debut at only 17 with Real Valladolid, quickly making an impression with the Segunda División club, his skills, field vision and set piece ability standing out alike.
Landáburu first appeared in La Liga with Madrid-based Rayo Vallecano, in the 1977–78 campaign. He contributed heavily to the modest team's maintenance of their top flight status during two seasons, after which he signed with league powerhouse FC Barcelona.
Landáburu moved subsequently to Atlético Madrid, being an automatic first-choice throughout six seasons (nearly 300 official appearances for the Colchoneros). At the end of 1987–88, however, mainly due to serious personal problems with elusive club chairman Jesús Gil, he chose to retire at the age of 33; still an active player, he majored in physics.
