I guess you were right because since these players left and PSG finally found Luis Enrique it seems they finally found the missing piece of the puzzle and now all things seem to be working in their favor. Individual names doesn’t always guarantee success, this is the same problem Real Madrid are facing now. Who would have believed PSG will be performing this good without the trio.
In the last few seasons we have seen PSG spending a lot of money to build a squad. Despite having a very strong squad, their performance was weak and erratic. The best players in the world like Messi, Mbappe and Neymar were in PSG's squad. But even then we do not see a good performance from the team. But now PSG's squad is not very strong. Even then the team is playing great.
Luis Enrique is a very experienced coach. If he had come to PSG 3/4 years ago, maybe PSG would have been able to win the Champions League title earlier. Even then, Luis Enrique has transformed a mediocre squad into a strong one. PSG is ahead in the race to qualify for the Champions League final. Hopefully we will see PSG in the Champions League final.
