Iñaki Williams has not missed a LaLiga game for Athletic Club since playing against Atlético Madrid on 20 April 2016.

On 20 April 2016, he came on for Iker Muniain against Atlético at San Mamés. The run of 187 consecutive appearances is just 15 short of the all-time record, according to AS. The Athletic striker will equal the Primera record set by legendary Real Sociedad keeper Luis Arconada on 188 when Athletic play Real Betis on 21 April and has the chance of reaching 189 a few days later against Atlético.

Juan Antonio Larrañaga, a former Real Sociedad midfielder, made 202 consecutive appearances for Real Sociedad in LaLiga between 1987 and 1991 and Williams will equal that figure in matchday 7 of the 2021-22 season provided he stays injury-free.
