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.
To build a stronger team is not easy because the coach must have a special strategy and maybe what happened at PSG was because they were given too much trust in star players. After Luis Enrique came everything was different and he did not privilege one of the players in the team so what happened was that the PSG squad became better than before. Nothing is instant because it takes a lot of things to drive a club's success, as Pep Guardiola did at Manchester City.
For the competition in Ligue 1, PSG is still a strong competitor whose dominance is difficult to break by other teams. If management gives time and lets Luis Enrique find the players he needs, it is not impossible that in the next few seasons they will become one of the candidates for the Champions League title.
