Honestly I think that PSG deserve to lose Mbappe at the end of this season. Because they are still quite inconsistent when it comes to team effort. They just can adopt a game focused on Mbappe only. Luis Enrique is trying to make this team performance increase but it happens only from time to time.
In one match they are playing really smoothly but in the other one they are just staying quite weak including Mbappe's effort as well. If we don't see a good progress during the season then there would be no reason for Mbappe to rethink of extending his contract too.
What PSG gets this season will really determine the fate of Kylian Mbappe, but unfortunately he will not think about the Ligue 1 title because he has already had it for several seasons, not only when he was at PSG but when he was still at Monaco he already got it.
The Champions League title is the target and it is the same as the target of the club owner, and the question is whether PSG will be able to get it this season? It's hard to predict because PSG will have difficulties when they enter the knockout phase because in the Champions League there are teams that are more solid than them in terms of appearance. We will see developments regarding the status of his contract at PSG, if he extends it then he will stay here but if there is no extension then he will move and Real Madrid will be the main destination, but many things could happen because he could change his mind.
People are very interested in Mbappe's future at PSG, which is fair. The guy is a bomb on the pitch! The Ligue 1 title might be nice, but the Champions League could be the big ticket. Yes, PSG is the best team in France, but what about Europe's top teams? That's a different beast altogether
If Paris Saint-Germain wins the Champions League, I really think they might have a chance to keep Mbappe. If they don't, though, there's no way to tell. Real Madrid, with its history and appeal, would be a tempting choice. The Santiago Bernabeu has been the home of champions, and now Mbappe joins them. It would be beautiful to see! It's hard to tell with sports, though, so only time will tell
