I have also observed that Real Madrid performance in Champions League is usually different from their La Liga matches maybe this should be due to the Anceloti influence who is gifted in the Champions League and the only coach to have won the champions league five times. This year they are still a big threat for any team as they will be playing to defend the title. They might have started badly with their La Liga but they have a fast way of putting their house in order to confront any opponent. Most definitely they will regain the consistency they are known for and will give Barcelona a big fight as usual.
La Liga and the Champions League will always be important for Ancelotti. But the Champions League always has great prestige for Madrid. They always perform great in the Champions League. Ancelotti always has a strong strategy for matches against strong teams in the Champions League. Madrid has a strength that no other team has in the Champions League. It is their champion mentality that I think they maintain in every Champions League match they play. It is like saying that they are the champions.
I personally will not always be fixated only on Ancelotti who managed to get five Champions League trophies because after all, Ancelotti also only succeeded when he was the manager of top teams like Real Madrid and Milan. But, when Ancelotti became the manager of other middle teams and some were also still top teams in different leagues, but in reality Ancelotti did not even succeed in improving the quality of the team in other teams in different leagues. Therefore, I think whether Real Madrid will succeed or not in the Champions League this season, it still seems to prioritize team performance first and cannot rely on just a few parties or players.
But indeed, when it comes to the Champions League and Real Madrid it is like something that is difficult to separate. Because after all, even though Real Madrid did not have good results in the domestic league but in fact, Real Madrid always managed to get good results in the Champions League and even, managed to get the trophy too. But I think this season might be more difficult, because with the implementation of the new format then of course it will make teams like Real Madrid also get different challenges, so there is still no guarantee for Real Madrid to succeed this season.
