Ousted from Bilbao due to the emergence of Ismael Urzaiz, Ziganda returned to Osasuna in 1998, helping the club to achieve promotion in 2000 and retiring after another top-flight season.

[6] Ziganda managed several of Osasuna's youth teams, including the reserves in 2005–06 and, after Mexican Javier Aguirre (also a former club player) left Pamplona for Atlético Madrid, he became the head coach of the main squad.

[9] In early July 2009, he became Xerez CD's new manager after the Andalusians had just attained a first-ever promotion to the top tier, replacing Hércules CF-bound Esteban Vigo and signing a one-year contract.

[10] In July 2011, former Athletic Bilbao teammate Josu Urrutia was elected as president of the club, and one of his first acts was to bring in Ziganda (who had been out of work for 18 months) as coach of the reserves.

[13] During his stint, several players made the step up to the main squad, including Yeray Álvarez, Kepa Arrizabalaga, Iñigo Lekue, Unai López, Sabin Merino, Enric Saborit, Mikel Vesga and Iñaki Williams.

[15] On 29 November, he oversaw a shock defeat to SD Formentera – a club experiencing their first-ever season in the third tier – in the opening round of the domestic cup, conceding the critical goal in stoppage time at the end of the second leg when a goalless draw would have been sufficient to progress.
