For just Ligue 1 he will not experience any problems because we are certainly aware that PSG's dominance in Ligue 1 is no doubt and they will definitely remain above other clubs for this domestic competition but Nasser Al Khelaifi does not want them to just get stuck in domestic competitions because after all, the club owner must want great achievements for his club so there must be a desire that coaches and players must provide as proof that money from the middle east is not burned in vain, so from this Enrique must prove himself that he is capable of being more bail than previous PSG coaches.
For Mbappe I think I will wait for this until the decision is completely finalized because the speculation is too much at this point.
If you only aim for Ligue 1, I think whoever the coach will still be able to win the domestic title. PSG is very strong and completely dominates the league. So it's not wrong if the club owner, Nasser Al Khelaifi, has high targets in the Champions League. With the quality and money that has been invested I think Nasser Al Khelaifi is at least targeting PSG to become Champions league finalists. And that is a target that Enrique should be thinking about because I think he can be replaced by anyone at PSG.
No matter how great PSG is in League 1, when they enter UCL Nasser Al Khelaifi's expectations will be faced with a difficult situation. Because PSG is starting a journey that is not as difficult as other European clubs. It's no wonder why the UCL will remain a mystery for PSG, yes you could say they are the most instant club in Europe. Recruited star players but was unable to win the UCL trophy. A big question mark is that here money is not a guarantee to be in the UCL circle, PSG needs to go through a long and bitter process in order to have its existence. For this season alone, maybe in the UCL for Enrique's troops it will not be much different from failing again, because the clubs they will face are much better prepared for mental matters of competition.
