That scenario is also still risky because it will depend on the results of other teams' matches, to be safer they must ensure 2 wins will be theirs in the last 2 matches they will play. In terms of calculations, that is correct, but once again it is risky, because no one knows the results of the matches they will play. It is quite sad to see a team with the status of defending champion having to fight hard in the last 2 matches, and that does not make them automatically qualify but most likely they have to go through the play-off round to be able to be in the last 16.
The target of winning can certainly be Real Madrid's target. Although the scenario I mentioned is still risky, but one win and one draw is quite reasonable if people judge Real Madrid's performance in the Champions League as not good based on the results received this season.
Against Salzburg and Brest, I believe that the result will be won by Real Madrid.
But it also still has to see the results of other matches, such as the team that is currently below them can win, including Paris Saint Germain and Stuttgart can win, then in terms of points they will have the same points. It is indeed a bit complicated to explain all this, but to be clearer maybe we can see from the results of the 7th match of the Champions League this season. After the 7th match, most likely we can see more accurately how Real Madrid's scenario is to be able to advance to the next round. But I myself hope they can do well, hopefully they can quickly get out of their internal problems.
