Real Madrid will be very hot next season just because of Mbappe's presence, but that doesn’t mean the Champions League will be easy for them. Just like you said, next season will be the last season for Guardiola at Manchester City, so he will do everything in his power to win the Champions League for the club before leaving, and we know Manchester City also has a strong squad. So I can’t really say Real Madrid will win the Champions League next season, but I know the season will be an interesting one that everyone will enjoy.
I’m also not expecting Real Madrid to win the Champions League next season because Manchester City and other clubs who are even tougher than Real Madrid are going to be fully ready for next season's Champions League. I believe next season will be a hot season, and again, I'm expecting Real Madrid to do more than they did last season because of the beast they have in their squad Now, Mbappe is a very talented player. He can do everything in his power to get the visibility he wants in Real Madrid, but what I’m also doubting is the trophy for the Champions League next season. I think it will be difficult for Real Madrid.
Looking at the superiority of quality, Real Madrid has more quality players and it is clear that their talent is under the tutelage of Ancelotti Real Madrid players are able to perform successfully. However, the competition next season will be fierce even though Real Madrid has recruited Mbappe, whose performance and talent are clear but there will be other teams who have the same high ambition to win the Champions League title. Real Madrid will not easily win the title again even though they have a big chance because there is Manchester City and I think they are able to compete with Real Madrid.
Of course, other big teams like Manchester City will not let Real Madrid dominate the Champions League again. Even though Real Madrid will do their best to dominate the Champions League I think there will be big and tough challenges for them that will prevent them from winning the Champions League title. who knows who will win the title next season only time will tell. but what is certain is that all teams have big ambitions to win the Champions League title including Real Madrid, which has previously won the Champions League title.
