Leaving the team? I think the right word for this is dumped because when you look at the treatment that happened to some of the players who left it did not imply they were leaving PSG, but PSG themselves wanted them to leave.
The example may not be far from 2 players (Messi and Neymar) many people blamed these two players last season for not being able to take PSG in a good direction and there was even an action where the fans were also anarchist when they came to Neymar's residence asking him to leave as soon as possible so with this we cannot say that PSG's condition is bad now because the players left considering the fact that they were the ones who expected it.
Their poor performance is the result of their previous actions and they should be able to accept that by not blaming the players who have left.
PSG fans treated Neymar badly by their action in his residence. The Brazilian is a good player but he has so many issues with injuries which affect his performance negatively. Messi was signed to help the club win the Champions League, so the club had to dump him when they failed to win the prestigious trophy. I don't also blame the management of PSG for letting them go because they earn so much money and their performance was not encouraging. But PSG is just blinded by the dream of winning the UCL, winning any trophy is a failure for the team, which is not right. The main problem now is that the performance of the club keeps depreciating even after the departure of these top players and Luis Enrique has not been able to fully maximize the quality of the players they have.
