The 2015-16 campaign was a season of dramatic, mid-season redemption for Real Sociedad as Urdinak navigated a turbulent start under David Moyes to secure a respectable 9th-place finish in La Liga under new manager Eusebio Sacristán. The year began with the astonishing, career-best form of club hero Imanol Agirretxe, who scored 12 goals in the first 13 matches, before a devastating ankle injury against Real Madrid tragically ended his season prematurely. Sacristán's arrival in November steadied the ship, guiding the club back into the top half of the table with a renewed attacking spark. It was a pivotal season that, despite the early turmoil, marked a successful rebuilding effort and the emergence of talents like Mikel Oyarzabal, securing a crucial top-ten status.
