Technically PSG players come from several clubs and have good abilities. So Enrique should only adjust and make the most of his abilities. I think for this season they are still quite capable of competing in Ligue 1. So they are still the Favorites for the champion. But for the UCL, since they are owned by Nasser Al-Khelafi indeed they have never been absent but they do not have UCL champions. The best achievement seems to be in the Runer Up position.
Luis Enrique has several world football stars in his squad and he just needs to adapt and try to mix things up to create a terrible squad. If they are only able to become strong competitors in Ligue 1 then in my opinion Luis Enrique is not much better than the previous coach because PSG's dominance in the League was already formed before his arrival. Management and fans are expecting more at this time from Luis Enrique and it is hoped that he can bring PSG in the competition for the UCL title this season.
Luis Enrique is faced with a huge responsibility and maybe realistically I also don't think they can achieve success in a short time in the first season Enrique came, he needed time to manage PSG and most importantly PSG entrusted him to recruit the players needed, not recruit players as they were they did before.
