I don't know why people are making this a big deal at least not as if they lost the match they only played a draw game, and somtimes a lot of things do fail during playing, I know by now they would have noticed their mistake and will definitely adjust am sure and now that they have new tactics with mbappe on board now they will need to just take note of the important things, and their team work will come stronger in their next game and we know Real Madrid we should know that they don't have any challenges and you can not say the king of champions league have challenges just because they played draw on their first game this is something that can happen to any club. The super cup was interesting because they did a great job even Atlanta played well to but I saw the coordination that Real Madrid came with to the pitch, and we are going to be expecting more games like that because I don't see any other person challenging Madrid for the la Liga title.
Ancelotti knows the matches to take serious and he does not mess with such matches. Drawing their first match is not a problem and will not stop them from achieving their target this season. I don't see any reason why one should be worried over Real Madrid drawing their last match.
