PSG is losing Mbappe and they lost Messi too, I think this team is losing the superstar players they had and I think there is even a possibility to say the PSG owner is disappointed with this team and they are going sell the players and try earning money from the players they sell there and decrease the salary they have to pay.
PSG was losing all of players that have brought so many supporters for PSG. This will be giving impact for long term. The income from the team will be affected as well. It's caused by PSG will not able to sell a lot of jersey, merchandise or tickets for people who have been willing to watch mbappe, messi or neymar. Losing all of superstars are big losses for PSG. PSG is now trying to get a new player to replace those superstars but the impact will not as big as them.
I remember when PSG got massive followers after signed messi in the club. We will not see that happens again this season. PSG has been losing its popularity slower but surely.
I saw some names that will be coming to the club but im sure if it will not change the image that owned by PSG right now as a club with bad environment in for the players.
Since the project now failed in a way it could indeed have consequences in the long run. The players that joined PSG in recent years thought that they will become a part of a project that will dominate the European soccer for many years and frequently win the Champions League with Mbappe, Neymar and Messi, but quite the opposite was the case. When PSG now reaches out to players the only enticement they have in their repertoire now is money. It will all be about the money. There is no Messi anymore and soon there will be no Mbappe. When players now go there it is not because they are playing with the best players in the world, but because they get paid more at PSG than elsewhere.
