About the "harmful" part, I don't totally agree. I understand what you are trying to say. But did you watch both legs of the Liverpool matchup? PSG were much better, right? The new version of PSG isn't joking at all in the Champions League.

I can say that Luis Enrique has rebuilt the team. The team is very, very good this year and we saw that again in the Liverpool match.
The team is no longer built on players, it is built on teamwork and they show us that every match. I am hopeful for PSG this year. It would not be a surprise for me if they win the Champions League.
The young talents and Dembele are doing very well this year.
The team's current manager, Luis Enrique, must be thanked for such an improvement in PSG's performance. Before Luis Enrique took over PSG PSG only spent money and they only saw failure but after this manager took over PSG he sold several players which made the club somewhat prosperous financially. I haven't seen Luis Enrique significantly buying any players like that so early in the season I thought maybe PSG would never do well with their current squad but as time goes on PSG are performing better under Luis Enrique. Maybe this season we can see PSG finish the Champions League in a good position. If PSG can qualify till the semi-finals at the highest I'd say it's still a big achievement for them.
