In the end, loyalty doesn't really suit a club like PSG because as long as he is not needed, he will be kicked out regardless of his previous player status and loyalty.
Verratti did have some options to leave last season as there were a few clubs interested in the player but he decided to stay but that doesn't seem possible now.
The latest news is that he is currently getting closer to the Arab club Al Arabi which is indeed a fairly easy move now.
PSG lowered his original price of 80 million to 45 million which made Al Arabi have no trouble bringing Veratti from PSG.
PSG team could not use a player like Lionel Messi well. One of the reasons for this is that the coach of the team does not have enough knowledge of how to use a player like Lionel Messi.
Even though I agree with you but my focus right now is still on Veratti because it does discuss some of the players who left like Neymar and Messi even though it was still very regrettable but seeing the fan treatment I think it was a good choice for big players like them to leave PSG.
In the end, the one who failed in this case was still PSG because they could not maximize well and demanded too much even though they deserved good results with several star players there but still the treatment of the fans and the arbitrary actions of the club officials I did not like this too much.
