Real Madrid or Manchester City. Don't try to buy quotes from scraps. European football is over, there are only these two teams 
I think the champions league is not just Real Madrid and Manchester City.
There is still Bayern Munich which is very strong. This season in the champion league in the group phase became an unbeaten team. although in the group it is also not easy because there is Manchester United too.
So a strong candidate for champion league champion this season besides Manchester City and Real Madrid, Bayern Munich is also a top tier candidate along with Real Madrid and Manchester City.
