Regarding the money spent so far, we know PSG for the money they usually spend on their palyer and they usually buy superstar players in each season but this time they made a good amount of money selling the players they had.
PSG spent 300m in this summer for players but they also earned 100m. On the other hand selling players like Messi, Verratti, and Neymar was a good step for them to earn more money.
Although psg did not earn much money from the transfer of Lionel Messi and Verratti, PSG earned a lot of money from the transfer of Neymar. PSG can easily buy a quality player from Europe for the amount of money PSG received as Neymar's transfer fee. PSG will not receive any transfer fee for the transfer of Mbappe, despite receiving transfer fees from those who left the club this season. Mbappe only wants to leave the club as a free agent member, Mbappe without the club as a free agent member means a big loss for PSG because PSG is not able to earn any money from the transfer of Mbappe where there is a lot of money to be made from the transfer of a player like Mbappe. PSG does not want Mbappe to leave, but if Mbappe leaves, then PSG will have to make a new plan and organize the team.
With their long fail experience now PSG management is learning good things and not buying big names which give them headache for spending more money on their luxurious salaries and other things which is positive change with the best thing happen they have one of the best and well experienced coach which is not going to have good changes and want to have good strategy which give them good results without big names so right now they are on right path and most chances they will be done better in Ligue 1 which is already under their control and their best target is Champions League which is never been easy because here we need good chemistry from players and better strategy from coach.
Even in this season we have no chance for them in Champions League but if they are able to stick with this coach most chances they could be big team in near future for the Champions League title as well, but this is never been easy as we can watch the success of Manchester City which is now one of the best in UEFA and World.
