If someone often watches the Champions League and Ligue 1 then it can seem very easy to judge because they used to have the best strikers in the team but there wasn't much they could do in the Champions League. In the Champions League, the strongest team may not necessarily be able to win, especially if PSG only relies on Mbappe individually because the Champions League is quite different from any other league, apart from experience it also requires collective player maturity.
For me, PSG is not the favorite team in the Champions League because there are many things they need to evaluate. Maybe we need to wait a few seasons so that Luis Enrique can bring PSG into a strong team and that depends on how management gives him the opportunity to manage PSG.
Favorites teams, Paris Saint Germain doesn't come close, it was 2 seasons back that we were able to sketch Les Parisiens as a potential club to win the UCL title. However they will keep making attempts until one faithful season, they will be crowned Champions of the UEFA Champions League which is regarded as the best trophy for club levels. Every UCL season, PSG makes it but they're unable to win the trophy, I keep asking myself this question repeatedly, why should we become surprised knowing fully well the standard of PSG and their incapability to win.
