Unlike you, I'm not sure at all about Enrique being successful in PSG. In fact, PSG had many superstar players in the last season they could help the team like Messi but they didn't have a good coach like Enrique in his team, Now when some players left PSG for the other teams, Enrique started working there but still I don't think if Enrique is enough to help PSG improve the team.
I think PSG still can't earn achievements in the Champions League.
But at least we have to give Luis Enrique chance to prove that he can advance to the next round. if PSG can qualify, maybe there is a slight chance of reaching the final, even though they will still lose because it too early for PSG to get the title in Champions League, but if about the title in League 1, PSG has a chance it is still very big to lead in first place in points table at the end of the season, even if you only rely on Mbappe, PSG performance seems to be quite strong and we remember the past when Messi was still at the club, the failure in champions league still the same as the previous problem, namely because it has not deserves the champions league trophy.
I think it is important to give Luis Enrique a chance. Getting the UCL in their first year has been hard for many leaders, even the best ones. So, calling into question his abilities this early on is a bit unfair. The odds are better for PSG in Ligue 1, though. I saw that they are only two points behind Monaco. They should still be able to win the title if they beat Brest, which I think they will. Even though they have failed in the UCL before with a star-studded team, let's not give up on them too quickly. This might be best handled with patience.
