This is still a problem and difficult for PSG to avoid because they with the power of star players even when there are Messi, Mbappe and Neymar also cannot promise to celebrate the UCL trophy. So we can conclude that UCL is not about a club full of stars, but about the mentality of all players, teamwork and what usually gives the most plus points is experience many times and understands how the atmosphere of competition in UCL. All of that PSG needs to have if they want to win the UCL, after several attempts until now it has not been fulfilled. Being able to dominate the Domestic League does not guarantee the same thing in the UCL, PSG still has to face teams with different strengths, mentality and cross-domestic clubs.
It is not easy to build a team to be able to win the UCL or compete fiercely with top European teams, as Manchester City only managed to win the UCL after a long process they went through to build the framework or foundation of the team so they could compete in the race for the UCL title.
While PSG currently does not have such criteria even though they have many star players, there is nothing instant in building all teams, everything has to go through a long process and PSG does not carry out that process.
Well, last season PSG had a lot of big star players like Lionel Messi and Neymar, but they didn't have a coach who was full of experience in the Champions League. And when they have a coach who has great experience but they don't have players who have the mentality to win the UCL trophy. I think they really need time to process to be able to compete more strongly with big teams from other leagues. For this season, PSG is still highly regarded by their opponents and I hope they can go well in every match they play. The winter transfer window will soon arrive where PSG can make the best use of the transfer market to be able to close the weak gaps in their squad.
If you look at Manchester City, of course they needed time to become UCL champions and their patience paid off by winning the triple winner last season. In this way, PSG can learn from them not to keep firing coaches because every coach needs time to bring their team to become champions, especially in the Champions League competition. Luis Enrique is a great coach, he just needs time to bring the UCL trophy to Ligue 1, therefore if PSG fails again this season they don't have to fire their coach.
