In fact, if you look at PSG in the Champions League there is nothing lacking because the star players are at the forefront. There is an important factor where PSG always focuses on gathering big players but does not realize that every star player wants to get more portion than what has been provided. Call it Messi, Mbappe, and Neymar who have achievements and still want to stand out more. So make no mistake selfishness will be seen from each player. For this reason, if PSG wants to be more effective in the Champions League competition, then don't just focus on gathering star players but must pay more attention to good management, both the coach and the team behind the scenes.
I fully support your opinion. because it's true that if PSG are only too focused on bringing in superior players or top players but don't look at everything else like can the coach understand the character of each player and should as a coach also have to educate players openly between all players what they want like a replacement a position or something that makes players more enthusiastic about bringing the PSG team to win in the champions league.
so it would be a waste if you only bring in new players who are strong but in terms of management or other things it's still disruptive. I think PSG haven't been able to reach the top of the UCL.
