After his brother highly recommended both coach and the player to arrange the deal, he accepted the offer and joined the squad in training.

He accepted the offer and stated that he had "heard good things" about his new team. However, he remained a fan of his former club Real Sociedad, stating that, although both sides competed in the second level, he hoped they gained promotion; he contributed with 11 matches in a return to the top flight, after a seven-year absence. In the 2009–10 campaign, Alonso began as a starter, scoring with a rare header in the second matchday, a 1–0 home win against Athletic Bilbao.
