Iñaki Williams qualified Athletic Club de Bilbao for the semi-finals of the Copa del Rey with a goal in added time against Barcelona at San Mamés, which seemed destined for extra time after 90 minutes tied but with the best chances for the visiting team, which was stopped by the local goalkeeper Unai Simón.
The young goalkeeper played a key role in resolving the match by stopping two balls that seemed like undeniable goals from Antoine Griezmann, who started the match on the bench, and Leo Messi, whose cross shot was repelled by Unai Simón after a great pass from Arthur.
But the play that sealed the match was the final cross from Ibai Gómez, who had just come on, from the right with his left foot, which Williams headed past Sergio Busquets and into the far post.
With this qualification, Basque football completes a historic day with the semi-final qualification of its two main teams, Athletic and Real Sociedad, eliminating in just four hours the two giants of Spanish and world football, Barcelona and Real Madrid.
