I think a team like PSG which has strong finances will not lose much and of course they will be able to quickly bring in the players left behind by Kylian Mbappe, although the quality will not be the same, but to get closer to Kylian Mbappe I think PSG can get him.
On the one hand, I see that there is also an advantage for PSG in losing Kylian Mbappe, this can make this team much more independent so that it doesn't always depend on Kylian Mbappe and focuses on building a team with an even squad in all lines.
Yes, they have very strong finances, so they will be able to do whatever they want, as long as they succeed in convincing the players they want to bring in. But I hope they don't do that, I mean they have to build a team based on team cohesion, not just individual ability. Individual abilities are very important, but don't let them become dependent on them, because if they are left behind by the players they will be confused again.
They have to build a foundation for their future, because until now they haven't done that, and it's possible that when they do that they will be much better than before. Luis Enrique is an experienced coach, I hope he can bring Paris Sait Germain to achieve something even better, especially in the Champions League. Maybe it won't be easy for them, but what isn't easy doesn't mean they won't be able to get it.
