You are not wrong I have to say. PSG were always like the team who always had the potential to win the trophy for the past few years but they were not able to. Maybe this season they have more probability to win but in order to win the CL, the stars have to align right and the team also needs to play well on the specific matchday. But so far what worries me is that the Messi, Neymar, mballe trio is still not gaining the needed chemistry, right?
I'm not sure PSG are currently capable of winning UCL. The arrival of Messi and Ramos was not enough to make them strong. PSG need the mentality to win, relying on their coolness will not be successful enough. They need the mentality of all the players to be with the champions. In two seasons, they reached the quarter-finals. But they always fail at the end. This season they have spent a lot of money, but in the knockout phase they will play with Real Madrid. It was a tough test, I still wanted Real Madrid to win during the match.
To begin with, it would be desirable for the trio of Messi, Neymar and Mbappe to appear together on the football field, because due to a number of medical reasons this does not happen, so to say that this bundle does not give the necessary effect is a sin against the truth

The current Paris Saint-Germain is really difficult to call an unambiguous favorite of the current Champions League draw, especially since the club got such an opponent as Real Madrid, which has gained good form in the national championship and is its leader. And there are still at least English clubs and Bayern Munich, which also have a good chance of winning the title. Therefore, if before the start of the season everyone called PSG the favorite of the tournament because of the transfer company and the presence of superstars, now the alignment has changed a little and everything does not look so unambiguous.
^ I think Mbappe, Neymar & Mess alone cannot win them the trophy, they need better midfielders in my opinion.
Because for a good attack trio to work well, they need better support from the midfield.
, who can assist them well. But so far they are lacking a lot of team chemistry and I still don't know how they will fix it.
