All this is logical, but if you look at history, it is no less logical that once every 20 years something unusual happens, like Leicester’s championship (in the Premier League) or Porto’s victory in the Champions League. Exactly 20 years have passed since this event and who knows, maybe it’s time for another “miracle” to come true. If the draw is the same as last year (in one part there are favorites and in the other outsiders) then the chance of some underdog to take the title will increase.
Well, let's keep our fingers crossed and see the club that would serve as a medium for the miracle you said to occur, we might suprisingly see Newcastle United that's been underperforming in the EPL win the Champions League trophy lol, UEFA Champions League is not a competition you could easily predict the winner from the beginning but there are some clubs im looking out for andc they're good performance has been consistente for the past two seasons.
Clubs like Realmadrid, City, Bayern Munich, Napoli and Intermilan, i have a feeling that one of these clubs might end up winning the league this season but im not sure of which but amongst all these clubs mentioned my two most favourites are Realmadrid or Manchester City and if you notice the performance of those clubs in the various league and so brilliant so far that's why my expectations from them in the UEFA Champions League is high.
I wonder how you can love Real and City at the same time? For me, these clubs are at different poles, I love one and hate the other

As for Newcastle, it won't be the perfect underdog that will win the Champions League (the Premier League is doing too well lately haha), but it's still better than the old set we've seen for the last 20 years.
In fact, PSG looks dangerous. I don’t like this club, just like City, but this season they have an even team that, paradoxically, will have better chances than last year’s “star” one with pensioners in the lineup.
Last seasons performance sure did promote a club like New Castle United to a league they could only dream of winning. At least, they get to increase their desireship if they perform and come out on top of their group.
This is international soccer, and I don't think Newcastle will find it easy playing against sides from other leagues mostly those who are not new comers to the champions let. It's going to be a hard fight for them, hopefully they make it to the Europa league, there they can shine but I doubt they would really do much. They just don't have the grit in the squad to put on an outstanding performance.
