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.
I think Xabi said something at the press conference to the effect that he hadn't had time to work with the team on the game against the buses yet. I think most people expected Real to win this game by at least 2 goals, but everything turned out as it did. By the way, Osasuna didn't make a single shot on Real's goal, that's good news, Real had obvious problems in defense and Xabi started from fixing them.
