I can say currently Manchester City is the only team we know they can have hope for the next Champions League title with Pep Guardiola because they are still in good form and they could stay stable and keep the main players they need for the next season. Also, Guardiola is improving the team and we can see even stronger Manchester City in the next Champions League season.
Haaland and De Bruyne are the best in the world. There is no better striker than Haaland and no better midfielder than De Bruyne in my eyes. For this reason, they are the favorites of this cup for me as well. However, this is a tournament and tournaments have different atmospheres. Also, teams like Real Madrid, who have a lot of tournament habits, can always change the balance. That's why I see Manchester City as the first favorite in the Champions League, but I can't be sure because in this tournament the best in the world are competing and they are fighting to prove to everyone that they are the best.
