Well, we know the money will not solve everything for PSG and we saw that in the last season because in the last season, PSG had players like Mbappe, Neymar, and Messi at the same time but still this team had disappointing performances in the Champions League and even in French league they have a close race with other teams until the last week while PSG invested much more than them. I think the best they can do is to give Enrique and the players they bought some more time to have a stable performance.
Actually, if they can manage their finances well, that can be the answer in my opinion.
For example, Manchester City or maybe now we can hope for Newcastle where with the money they manage well the difference in performance is clearly visible, it's just that for PSG they do have a lot of money that they can use as resources, it's just that they can't manage it well so they seem to just waste the resources they have. Their players are very good from individual skills, it's just that when club management is not good starting from staff and coaching that cannot keep up with players, the resources they have in terms of money and quality players will not affect anything.
