Since they are in a team that won the UCL this year, their departure to another team would only be valid for players who have less playing time at PSG. Otherwise, it would not make sense for a player who is in the main squad of Paris Saint-Germain and plays constantly to go to another team. Because Paris Saint-Germain is now a team that is the Champions League champion. They have achieved the medal that every footballer dreams of and they will fight for it next year.
PSG is in perfect shape, they won the trebble including the UEFA Champions League, it shows how strong they're so I don't believe that Enrique would disorganize the team by selling his key players, he might sell or loan out some academy or bench players but his first 11 stays. I believe their would be few additions cause even the strongest teams still need to strengthen all areas of their squad against the upcoming season, it's even the right team to do cause a team that's to defend the Champions League next season needs to be fully ready, if you notice, Real Madrid and other top teams that didn't really perform well in that tournament are really getting prepared in the transfer market, PSG is watching them so I believe they too would recruit some few additional players to strengthen their depth.
