The only goal of the match was scored by Madrid through a penalty. There is no denying that Madrid was lucky. Scoring in this match was a big challenge for Madrid players. The players needed time to adapt to the match strategy of the great Xabi Alonso. And secondly, Osasuna played very badly defensively in this match.
Osasuna only had 2 shots in the whole match. I saw Osasuna take their first shot in the 43rd minute of the match. There was no interest in scoring among Osasuna players. Every player in the squad played the role of defender. It is very difficult to score against such a team.
Real Madrid dominated the match. If we thought we would see several goals from Madrid. 71% of the ball possession was by Madrid players. A total of 18 goals were scored by Madrid players. Hopefully, the performance of Madrid players will be sharper in the upcoming matches.
This was a very unsatisfactory result for Real Madrid in their first week of La Liga, especially in their opening home match. I even considered the goal disallowed, as the Osasuna player didn't foul Kylian Mbappé. The Osasuna player didn't touch Mbappé at all, but Mbappé himself deliberately fell.
From this match, I saw Real Madrid's finishing was very poor. They had many good chances to score, but failed to capitalize on them. As for Osasuna, they displayed a fairly strong defense, their defense was quite difficult to penetrate, even forcing Real Madrid players to attempt shots from outside the penalty area.
Not only was Real Madrid's finishing poor, I found their midfield to be quite weak. Modric's absence in midfield was entirely visible. Madrid needed an experienced midfielder. But now Madrid's squad doesn't have any experienced midfielder. This will be one of the biggest feebleness of Madrid's squad this season.
However, Madrid's defense seems to be very strong. Although Osasuna's players didn't attack much in this match. So we still don't know how Madrid's defenders will perform against big teams or strong attacking units. But Madrid's new three defenders Carreras, Huijsen and Alexander Arnold have probably adapted well to Alonso's tactics.
