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.
With Mbappe, Real Madrid will have a perfect attacking. They will have 3 great attackers for the next season (Mbappe-Vinicius-Rodrygo). Real Madrid seems to play again with the formation 4-3-3 because they already get their ideal striker with Mbappe. I hope Real madrid can be more offensive in the next season.
