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.
This credit you’re given to them can only be so because of their outstanding performance in the last season’s champions league competition. We don’t know how this upcoming season’s champions league is going to go well for them, but we can conclude now that they’ll go far and make it to the knockout stages. After that, their performance when the next season begins will determine how far they’ll go in the champions league or if they can still retain the title for the second time consecutively..
The champions league as the name indicates is not a farmer's league that we can easily assume that because a team outperformed in the previous season and won the title same event will reiterate itself, of course it has happened with the likes of Real Madrid having it back to back but it wasn't that easy and no one saw it coming either. City as sure to do so well next season but winning the title immediately again is what doesn't seem possible, if you take a critical look at the transfers of usual favorite teams in UCL like Barcelona, Real Madrid, Bayern Munich it will scare you to agree that City can win the title again next season.
