The PSG team has implemented many strategies to do well in the Champions League. But so far it has not been successful. It remains to be seen what kind of changes this season will bring.
The aim of the changes made by PSG is to be even better than last season, but everyone will probably see it next season, because one of the strikers that PSG relied on very often last season will not be seen again next season. So that PSG must be able to replace the vacant position with another player whose talent is not bad so that it can be better suited to the striker who will still survive next season, namely Neymar.
I do not see many strategies that PSG implemented to be able to win the Champions League apart from signing 3 supers stars in the same club and giving one an over priced contract thereby setting the whole team in disarray.
If PSG really want to be prepared for the Champions League challenge they should also look at quality defence and midfield.
