Real Madrid played at home and only scored 1 goal.
I didn't watch the match live, but watching the replay on YouTube, I saw that after Kylian Mbappé scored from a penalty kick, Xabi Alonso looked dissatisfied.
Of course, the coach was dissatisfied with Real Madrid's poor performance, wasting so many chances.

If Real Madrid continues like this, Barcelona will easily dominate the top of the standings and win the title again this season.
