Xabi Alonso has signaled that he will be making changes to the squad. He believes some things need to change within the team after the PSG match, and I think he's right. Real Madrid shouldn't lose 4-0 to any team. There are many star players on the team, but teamwork is what matters. I think one of the first things Xabi Alonso will bring to the team is a strong sense of teamwork.
When you're playing against big teams, defensive mistakes become irreparable. The fact that Real Madrid's defense makes such simple mistakes is a major problem.
Xabi Alonso really needs to fix this before the season starts. There was something wrong with the strategy he employed in yesterday's match. And the team chemistry wasn't good either. Poor teamwork will only result in poor play. Even if a team is filled with many star players, without good teamwork, it won't change the situation or make the team better.
Besides the poor defense, I think the blunt attack was also a problem in yesterday's match against PSG. The midfield didn't look particularly good either. So I think Xabi Alonso really needs to improve everything there. But it's not about the players in the squad. It's about teamwork and perhaps the strategy employed. Because, in terms of squad depth, I think Real Madrid is already quite good.
