This can be one of the reasons that makes sense actually because looking at the current condition of PSG they don't seem to have a condition that can be proud of in terms of their management which makes the money they spend seem to be useless.
Even though we know that the Champions League is not a place that anyone can enter but should be with PSG's finances they can talk more than now.
They always focus on ready-made players is also one of their tendencies to struggle a little because they always buy old machines like Ramos or Messi, which even though their names are unquestionable but their qualifications are clearly reduced due to age.
In addition, when the competition factor is also lacking in the domestic league, I think this makes their conditions more difficult when they are in tough competitions because if you look at other competitions such as La Liga or EPL it can be said that the competition in Ligue 1 is much easier which makes them accustomed to competitions that are not too difficult to make them fail to adapt to high competitions such as the Champions League.
PSG still didn't succeed in the champions league last season even though their squad last season was quite strong. But yes they failed to show their best power in last season. Even Neymar had to be absent and that was one of the deficiencies that might have greatly impacted their performance in the Champions League last season. For next season I think PSG is still very much counted as the strongest team in the Champions League. Mbappe has found a new front line duel for next season after Asensio joined in this season's transfer window. I think Neymar will also stay with PSG for next season so their front line is still very strong for next season. Even though Messi has left, PSG still has a pretty good sharpness on their front line. PSG only needs a coach who really understands to lead them to become the strongest team in the Champions League next season. After Galtier was fired it looks like Luis Enrique will become coach for PSG next season after Fabrizio Romano confirmed that PSG had reached an agreement with Luis Enrique.
I also think the same because PSG will definitely continue to be reckoned with, but everything will be the same when they only focus on what I said before.
Now there is a bit of a difference from them in terms of transfers because looking at some of the players who have come this season for PSG such as Asensio, Lucas Hernandez, Lee Kang In and Milan Skriniar at least they are not looking for players over 30 years old as before especially with Asensio who is actually still very good or the defensive strength of Lee Kang In in the previous world cup is quite good and of course we know Milan Skriniar has also been quite good at Milan this can add to their strength.
It's just that still in this case their mindset needs to be changed especially with the significant differences in Ligue 1 and the Champions League in terms of competition of course they must be aware of that because if they only equate Ligue 1 and the Champions League forever PSG will be the same and cannot develop in the Champions League even though they are one of the favourites.
