As the volatile Reyes became increasingly disgruntled with his reserve status at the club, Adrián firmly established himself in the starting eleven. In two games separated by only five days, he scored four goals, two apiece against Real Zaragoza in the league (3–1 home victory) and Udinese Calcio (4–0, also at home) in the Europa League; in the latter competition, as the team reached and won the final, he scored 11 times.
