This is likely to happen when the matches start to get busy where PSG will face a lot of competition which makes Enrique have to think hard about adjusting players in rotation and maintaining performance.
In addition, their opponents are also not too strong so PSG cannot be complacent for the victory they should get in this match.
For now they may still be comfortable but towards the middle of the season if their performance does not falter then indeed Enrique proved that without Mbappe he can mix his squad better.
I can't see how it will ever be impressive when PSG beats their opponents in Ligue 1. It will always be David vs. Goliath given how huge the financial advantage is that PSG has over any other team in the league. It is literally like buying 3 points and Enrique will once again be judged by the Champions League only. Nobody really cares about the Ligue 1 title. Enrique probably doesn't care though as his salary is probably quite impressive. If he gets fired, he will be rich and if he doesn't get fired, he will still be rich. But if someone is a highly ambitious coach, I think PSG wouldn't necessarily be the club that a great trainer wants to take responsibility for. It's a pretty boring league and it doesn't feel like a huge achievement to win the title when you can just pump billions into the team whereas nobody else can do the same.
It will be a different story if this happens in the Champions League especially when they can outperform some big clubs who are subscribed to the current champions then it can be an extraordinary thing even Enrique can be said to be able to change the philosophy that PSG has by not relying on their star players at high prices to get optimal results.
Consciously or not until now PSG is still required to do that and if in the end in the Champions League they don't do well then it could be that any form of good performance in Ligue 1 will not be considered a big achievement for Enrique and PSG.
