The 2021-22 campaign for Athletic Bilbao was a season defined by deep cup runs and domestic consistency under manager Marcelino, culminating in an 8th-place finish in La Liga. Los Leones, in their 91st consecutive season in the top flight, reached the semi-finals of the Copa del Rey and finished as runners-up in the Supercopa de España after a valiant effort against Real Madrid. Leading the charge was the relentless forward Iñaki Williams, whose 8 goals were key, and who achieved the incredible feat of breaking the long-standing La Liga record for consecutive appearances. This memorable year, which included a dramatic 4-0 demolition of rivals Real Sociedad, solidified the club's identity as a formidable cup challenger.
