A big name is just a name, in fact PSG still can't do much even though they have several players with big names, their main problem is the selfishness of their players when PSG has star players in it they really privilege the players and make other players not play optimally because other players feel less confident and they rely on star players to appear stunning in every match, but now PSG no longer has star players who are always privileged now they have players who are no less good than star players and they are treated fairly, so they can work together solidly, if PSG continues like this maybe they can compete well in the UCL and can go further.
I agree with you that big name is just a name. If the bonding between the players in the squad is not good, there is no experienced coach, then even if all the players in the squad are star players, it is not possible to get good performance from this squad. And PSG club can be seen as an example of this. PSG had the best players in the world. But even then this team failed to play well in the Champions League. But this season's scenario is completely different.
This season we see that there is no big star player in PSG's squad. Even PSG lost a player as talented as Mbappe. However, we have not seen any deterioration in PSG's performance. Rather, we see a better performance from PSG this season.
However, PSG's performance has stabilized with the help of Luis Enrique. The bonding between the players is very strong now. PSG's match strategy is also excellent. So PSG has a chance to perform well in Champions League this season.
