The 2011-12 campaign was an unforgettable, yet ultimately heartbreaking, season for Athletic Bilbao, with the club finishing 10th in La Liga. Under the intense, revolutionary guidance of manager Marcelo Bielsa, Los Leones played a captivating, high-pressing style that carried them to the finals of both the Copa del Rey and the UEFA Europa League. Spearheading the attack was the prolific target man Fernando Llorente, whose 29 goals across all competitions (17 in the league) powered an unforgettable European run that included a famous victory over Sir Alex Ferguson's Manchester United. Despite losing both major finals 3-0 to Barcelona and Atlético Madrid respectively, this season remains a defining chapter of 'El Loco' Bielsa's brilliant and frustrating legacy.
