I think the target routine of PSG is like that. They did well last season, but they cannot necessarily do it in the new season. Last season, we could see how some strong teams in the Champions League had problems with performance. Like Madrid and Man City, who I think did not perform optimally.
The new season will be a new challenge for PSG. Ligue 1 may not be a problem for them, but the Champions League is always difficult to predict.
Yes, for PSG to achieve what they achieved last season, I don't also think it will be possible for them in the upcoming season. I just view that PSG was opportuned last season for winning champion league despite their hard work, as some teams were not at their best, as you said especially teams like Manchester City, Real Madrid, and even Liverpool. So, trying to win those titles again will be quite a challenge for them. In fact, looking at their squad compared to the three teams I mentioned, I don't think PSG measures up. Those three teams have great, world class players and with the way teams are strengthening their squads now, next season Champions League may be a very big challenge for PSG to win champion league again.As you said about Ligue 1, I also don't think they will have much problem winning that or other competitions under the French leagues.
