A week after the French superstar failed from the spot in the Champions League against Liverpool, he endured further misery from 12 yards as 'Los Blancos' defeat allowed league leaders Barcelona to retain their four-point advantage. Alejandro Berenguer fired Bilbao ahead early in the second half, with Jude Bellingham levelling for Madrid before Guruzeta's decisive goal.
"A big mistake in a match where every detail counts. I take full responsibility for it," said Mbappe in a post on social media network Instagram. "A difficult moment but it's the best time to change this situation and show who I am." Madrid coach Carlo Ancelotti said the forward was downhearted after goalkeeper Julen Agirrezabala saved his penalty.
"Obviously (Mbappe) is sad, disappointed, but he has to continue," the Italian told reporters. Mbappe has scored 10 goals in his first 20 games for Madrid across all competitions but is struggling for consistency.
