Ernesto Valverde did his former club Barcelona a favor on Wednesday night as his Athletic Club side beat Real Madrid 2-1 at San Mames.
Álex Berenguer put the hosts ahead shortly after half-time but Madrid had a great chance to equalise when they were awarded a spot-kick.
Kylian Mbappe stepped up again for Real Madrid but, just like he did against Liverpool in the Champions League, failed to find the back of the net.
Madrid did find a way back into the game through Jude Bellingham, but Athletic Club won it late on through Gorka Guruzeta.
