Real Madrid have always been a good team in the Champions League, and I believe they will continue doing that as long as they will continue to be with Ancelotti. The Champions League competition is in their body already; they have been doing very well in the competition. We will see how they perform next season again, although I know the arrival of Mbappe will surely bring more positive changes from next season, so I think we should be expecting another Champions League trophy from next season.
At some point Madrid even makes it feel like the champions league is a domestic league in the way they always get to win the league titles too frequently, they are very good and have a very good and functional tactic they use on the champions league which keeps producing the kind of results they get for them. The fortifications they are making on the team makes them even more potentials to winning the league again even in subsequent season provided they still have all of their functional strategies in place only that they may at some point have a change of coach and I know that is going to affect them a whole while, but then the strength of the squad may likely not drop only their technicalities is going to change.
The Champions League competition with the domestic league is clearly a very different competition, This doesn't mean that Real Madrid has won more Champions Leagues than other clubs, making the UCL competition easier for them despite the fact that Real Madrid sometimes still has difficulties
Real Madrid won the La Liga title 36 times while the Champions League 15 times means that the UCL is still very competitive for other big clubs and Real Madrid is not the only strongest club there.
I admit that Real Madrid still has a stable performance every season, it's difficult for any club to beat them, that's what makes them survive so they don't give up easily, but that does not mean that the UCL feels like a domestic league. In my opinion, the UCL is still the most difficult league among the others.
In the Champions League, I didn't see any club that will challenge Real Madrid unless it was Manchester City, but we don't know about next season if they will have a club that will definitely challenge them and win them on the pitch, but it will be very difficult to find a club that will challenge them because the squad that Madrid has, I don't think they have the best players in any European league, but we don't know about the features. And I am confident that Real Madrid or Manchester City will remain the favorites to win the Champions League due to their experience and great players. So, any team that wants to compete with the team must obtain youthful talents players in the club. So any team that what to compete with the team need to get young stars and better coach like Ancelotti or Guadiola. Because is there time now, am just waiting how xabi Alonso will perform in the UCL with Bayern Leverkusen let see if the club can challenge Real Madrid in the competition if they meet each other and see if they will get chance and win them.
