I think that is an obligation that other teams have to do and maybe it requires strategy to a decent squad depth to be able to do it. If any team makes it to the final round and faces Real Madrid then it is clear that they will not be able to win the title and Real Madrid will be the champions. Therefore, before reaching the final round, Real Madrid must be knocked out in the quarters or semifinals because otherwise they will continue to dominate the Champions League.
Like last season where Manchester City eliminated Madrid before the UCL final and finally Manchester City became UCL champions for the first time stopping Madrid's dominance in the UCL by beating Intermilan in the final, but unfortunately last season Manchester City failed to eliminate Madrid. There was a clear opportunity for Madrid to chase the trophy. The UCL went smoothly and beat Dortmund in the UCL final, but in the new season there will be many surprises and I also hope that not only Manchester City but there are other teams that can beat Madrid but no one has been able to beat them except strong teams like Manchester City or Munich. Moreover, Madrid has the new strength of Mbappe, it is clear that it will also make it difficult for other teams to break their dominance in the UCL next season.
Exactly, that's the real picture and maybe that will continue to happen as long as no team can overthrow Real Madrid before the final match. Maybe there is a little hope for other teams to win against Real Madrid in the final round but it feels very difficult considering that the last time Real Madrid was runner up was in 1981 and that is still the longest record for a team competing in the champions league.
I think that even though there are always strong competitors as you have mentioned, it will still be very difficult if the team cannot beat the winning mentality that the Whites squad has. Just imagine, when Real Madrid concedes, they can always equalize or reverse the situation and if there is a team that can make Real Madrid feel frustrated then that will be an extraordinary thing and maybe Real Madrid will not be as strong as before.
