To be honest, I prefer PSG without Mbappe because now PSG can focus on building a squad that is evenly distributed across all lines without being able to just hope or depend on Mbappe alone.
Luis Enrique is a very experienced coach and has good qualities, and I am sure that if PSG management gives full support to Luis Enrique then he will be able to build this team to be much better in the next few seasons.
You are right, when Paris Saint Germain is without Mbappe maybe they will be able to dig deeper into the potential they have and can focus on developing the team rather than just managing one player. Paris Saint Germain wasted their time just dealing with Mbappe, how they tried to persuade Mbappe to stay, but it was of no use at all because in the end they had to really lose this player.
If only they could focus more on the team rather than trying to keep Mbappe, maybe they could be better prepared now. However, it is quite difficult to make them realize that there are still more important things they can do and after they really lost it, I think they are now aware of what they have been doing all this time. Now there is no time for them to regret players leaving, they have everything to build an even better squad, so I hope they do well and soon forget what happened to them recently.
