What's the point of spending a lot of money when you get the same result every year. That simply mean they are doing it the wrong way.
PSG needs good talented players that are consistent in their performance, not too much injured like Neymar, not old as Messi, with all respect to what he did with the team this year.
PSG will spend for new players for sure this summer, hopefully they can add something to the team.
I agree with you, if they keep getting the same results for spending a lot of money, then I'd say they are better off not spending any money at all. Something is wrong with the way they run the club to make this happen. I really regret it when a team with very good financial conditions can't do much in a prestigious competition, I won't talk about them in Ligue 1, because obviously in my opinion this is not a place for them to compete on an equal footing. Maybe one or two seasons when they are like this, then it can be said to be a natural thing, but when every season they do the same thing, then there are questions to be asked.
But why do people think that when you run a project like PSG in an inferior domestic league that the club can then compete with clubs from the Premier League or even La Liga or the Bundesliga? PSG lacks competition throughout the year, which is a big issue for them because they have to switch gears in an unrealistic manner to beat Manchester City after they have played 10 games in a row against very weak Ligue 1 teams. They don't have enough exposure to opponents on a very high level and that can't be changed no matter what management has control over the club. It is a major disadvantage of building a club in an inferior league.
They should be able to do that with the power of money they have, it's just that even though they want to, it's like they never learned from the mistakes they made before, in another sense, nothing changes about them from season to season, starting from the scheme, how to play, and how the strategy they're on transfers.
Apart from that, the league they participate in also seems mediocre for Ligue 1, of course they feel like this is necessary without extra effort for Ligue 1, but when talking about bigger competitions, of course something like this won't happen.
