yep, indeed PSG will not worry about their finances in order to improve every line and it has been proven that they are not only retaining Mbappe but also trying to get new players with good performance such as Dembele and also Marco Asensio who will help strengthen the attack line and I see new players this has a good contribution and can strengthen chemistry with mainstay players like Mbappe.
I believe that this season PSG will still appear strong, but in the next season I cannot be sure whether PSG will still be strong after Mbappe departure.
Looking at the competition in Ligue 1 where there are not that many competing teams because it is only dominated by a few teams, it is actually not impossible for PSG to remain a strong team in the local competition even though Kylian Mbappe left the club to join another club.
PSG's owners will immediately look for a replacement for Mbappe and he may not have the same abilities as Mbappe, but as long as the striker is able to score lots of goals then he will be able to keep PSG as a team that dominates Ligue 1.
PSG's financial capabilities will give them the opportunity to get the players they want, maybe they will be like when they saw Mbappe's talent at Monaco, meaning they are looking for talented young players who will be able to develop well at a club like PSG, but PSG must change the way they build their team so that they can also more competitive in Europe.
