Iraizoz rarely missed a league game in the following years. On 16 January 2010, his "Player of the match" performance helped the team hold on to its early home lead against Real Madrid, constantly denying Kaká and Cristiano Ronaldo's efforts. Additionally, he was in goal during the 2009 and 2012 finals of the Copa del Rey lost to FC Barcelona, and also helped defeat that opponent 5–1 on aggregate in the 2015 Supercopa de España for his only accolade at the San Mamés Stadium.
