Real Madrid played well against Osasuna. The problem Real Madrid had in that match is that Real Madrid didn't create good chances against Osasuna, and it made Real Madrid not score plenty of goals against Osasuna. I know it's too early to judge Real Madrid, but they need to create good chances in their next matches if they want to beat their opponents easily, but if they continue with how they played against Osasuna, they will find it difficult to win their matches this season.
Yes, it looked like Real Madrid were struggling to create clear chances in that match. Of course, they were struggling to create any clear chances because Osasuna's defenders were excellent, keeping a tight lid on Real Madrid's attacking players, which ultimately made it difficult for all of Real Madrid's key players to score.
It's true that Real Madrid needs to improve, because if they don't, they'll definitely struggle to win in future matches. I hope Xabi Alonso can improve Real Madrid, and of course, if there weren't a penalty kick, I think this match would have ended in a draw. Real Madrid's next match will be against Real Oviedo, and they should have won easily. However, I'd bet on Real Madrid winning that match. What about you? I hope Real Madrid scores a lot of goals to make the match even more exciting. I think Xabi Alonso is really being tested because of course coaching at Real Madrid is certainly not easy because the demands from Real Madrid fans are very high who want to see Real Madrid win trophies this season.
There are a lot of new faces at Real Madrid, and they are currently in the adaptation phase, so give them a little more time, and I think that will give them the opportunity to have good chemistry and become a solid team. This victory is not satisfying, but I see that they have a different kind of football than before, and that is a positive thing. The most obvious improvement is their back line which now looks solid, and it's almost no longer visible sloppy in ball possession.
Osasuna played a very solid parking bus strategy, and because of this, Real Madrid is having a hard time scoring goals. Apart from that, the absence of Jude Bellingham has quite an impact on the creativity of their midfield.
