Real Madrid had formed a strong team but injuries messed up all their plans. They bought Mbappe and released Toni Kroos from their club last season to play Jude Bellingham in midfield. Valverde has problems, so Real Madrid's plan may be different in the upcoming matches.
Real Madrid have plenty of support players but without players on their bench who are at least as skilled as those who have performed in the starting XI in important matches, it will be challenging for them to win against any team. But the defense is still strong, so this defense is now the hope of Real Madrid.
I think their record does not show that this team is weakening. if you look, in the first 10 matches, there are only 1 defeat and 2 draws. I like their performance and strength.They continue to play with such performance in the next matches and there are difficulties in the match but there is a way to deal with them. Only strong and smart team players can do it. The game is different in every new league some teams will look good and strong now. But this complicated was weak in the league. Real Madrid may lose to some strong teams but they have also beaten some strong teams. if you look at their record this season, you'll know.
