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.
Injury slightly made Real Madrid's power problems but over time Ancelotti tried to finish even though he had to install it not a core player. I believe he is able to solve the problem because indeed into the squad owned by Real Madrid is slightly better than other teams. But because a few matches that ended were not satisfactory, Ancelotti had to find a way to deal with these conditions.
Facing Dortmund is not easy even though Head to Head Real Madrid is still superior but now they have to really work hard so that they do not experience defeat like when facing Lille, even though if you see the opportunity Real Madrid should be able to win the match.
What is happening to Madrid at the moment is not a small problem in my opinion, they are missing a lot of key players at the moment and have to face a tight schedule after the international break, so that of course makes Ancelotti job very tough at the moment, in two days they will face Celta Vigo, indeed that the match looks easier for Madrid to win, but they only have 3 days to rest before facing Dortmund in the UCL, maybe Ancelotti can overcome the challenges they face but if they continue to play young players and also reserve players of course their chances of winning the match will be very small, although indeed Ancelotti is an experienced coach who has proven his ability to manage the team in various difficult situations, but with the storm of injuries that befall them at the moment it is clear Madrid chances to consistently achieve victory is very small in my opinion,So far Madrid has a better head to head over Dortmund, but the current condition clearly cannot be our reference to favor Madrid in the match.
