That should be the case and they should be able to learn from Manchester City to build a team not in an instant way by recruiting lots of star players, PSG failed last season when they implemented this.
And I also see that they have not developed or have not been able to achieve achievements on the European stage because PSG does not have fierce domestic competition so this team cannot compare in strength to be able to rise even better.
As we have seen in the last few seasons in League 1, no competitor has put pressure on PSG in the title race.
This is what still makes it difficult for PSG to measure their own abilities when they are on the European stage because the opponents they face in League 1 are quite weak opponents and cannot put that heavy pressure on PSG. If only PSG could get enough opponents in League 1 every season, perhaps PSG's own strength would not be what it is now and could even improve more than it is now. So when PSG faces other teams on the European stage, they will become more accustomed to withstanding pressure from their opponents.
Yes, with the uncompetitive level of competition in the domestic league, they will be surprised when they find opponents who are better than them, that's why Paris Saint Germain is still having difficulty on the European stage, especially the Champions League. If they get a very competitive opponent in Ligue 1, I'm sure they will be even better than what we see now.
Being in a difficult situation like this is not easy, because this is also not what Paris Saint Germain wants to be in a league that doesn't have very tight competition, so it will be difficult for them to develop. And one more thing, what I see from Paris Saint Germain is that they still rely on individual ability rather than teamwork, so that is what ultimately makes them difficult. The reason is that most of the big teams in Europe rely more on teamwork than individuals, and when these teams meet we will see quite striking differences.
