I also support your opinion that PSG's shortcomings are not in the coach but in the players and also the new environment that they have to adapt to in order to make the right decisions when competing in either the domestic league or the campions league. Enrique is a coach who has experience in facing the big teams he coached before coaching at PSG. The enthusiasm of the players should also be able to adapt to the formation set by a coach in order to match several previous records. PSG's problem is not with the coach, they have to better organize suitable player positions after Mbappe left for Madrid. PSG seems to have lost a key player.
The environment of League 1 is different from the environment of other major leagues and that may be one of the factors that PSG cannot play competitively in the Champions League, not because of the coach because so far PSG has always recruited famous coaches in Europe but still these coaches cannot make the PSG club perform well in the Champions League, they are only strong in their own league. In my opinion, the player, coach and environment factors have a big influence on the team. I think if League 1 the clubs can provide fierce competition to PSG, maybe this club will be tougher in setting strategies so they are used to the tough environment and when in the Champions League competition the players have a strong mentality to compete.
