You had a very good team before Neymar and Mbappe, definitely a better overall squad but will these superstar's be happy in L1 long-term? Probably not imo, maybe without the Neymar and Mbappe's you could finance the Thiago and Partey deals and many others.
You really should become the Bayern of France, in that you get the pick of all the best French players, because the talent in French football is outstanding, and from the outside looking in you are currently the biggest club in France by a mile.
You don't get it.
We can't get Thiago or Partey deals because they prefer playing in PL. When a player like Partey prefers going to Arsenal without CL football rather than going to PSG, you can understand how much an hurdle L1 can be. Bayern is moaning because Thaigo Alcantara has agreed terms with english sides and they don't wanna pay the 30 M. Do you think PSG wouldn't be interested in him ?
So, as it stands, it is ironically easier to get top picks of the highly priced players than the top picks of the more affordable players for PSG.
And i agree with you about the fact we should become the Bayern of France but French people don't have the same mindset with the German. Look at all the good players Lyon has unearthed and how many went to PSG. Aulas wouldn't sell us anything unless it is really overpriced. Same with Monaco, OM obviously. Contrary to Bayern, we are being milked in our domestic market so much that we have few french players and it is more affordable to buy players from abroad. Even our very own players from our academy are ungrateful, we can't expect much from the other clubs french players. In fact, i would even say that foreign players have more respect for our league than french players. Then, you add the "Poulidor" mentality (people liking the underdog story) and the Qatar ownership and you can easily see why PSG isn't love as much as it should.
We only have 1 very good french player in the team and it is Mbappé. You have to remember that Mbappé only joined PSG because he absolutely refused to join Real Madrid at the time despite Monaco Vice President wish. And it was for 180 M (with all bonuses). To get a player like Aouar or Camavinga, we have to hope the same mindset from those players and it won't happen. Hence why Aouar will join Arsenal for a moderate fee while our midfield is dogshit.
PS: about our team before Neymar/Mbappé, the season before they arrived is the last one when we didn't win L1 title. The season we lost 6-1 to Barcelona (despite dodgy refereing we were shit).
If you are thinking about the seasons before that, well, we had Zlatan at his prime. You should notice we didn't win L1 the season before Zlatan/Thiago Silva/Verratti joined. It seems we simply cannot win the league without a very strong attacking superstar. We definitely played better at this time but it was Laurent Blanc style (Barça lite, his Bordeaux was playing cool football too) and we actually had a good midfield with Matuidi, Motta, Verratti. Two of those players have not been replaced adequately to this day, explaining our decline.
