This is indeed quite an impressive game from the PSG team but I don't really think that they have risen because I think what PSG showed is very reasonable because the opponents they faced were of far lower quality than them so it is only natural that the PSG team's game develops as well as the players.
We will never know the extent of PSG's strength if it is not when they play against strong teams.
And regarding Kylian Mbappe currently being the player most feared by opponents, of course the opponents who will face PSG will use various methods to stop Kylian Mbappe's movements so that because of this it makes other PSG players more profitable and free.
I don't measure the strength of a club in their various domestic league games, when they get to big European fixtures, how they play and handle games are what matters. But in terms of big side in league ¹, they remain the best side still regardless of the fact that they've had a bumpy journey to the top since the appointment of Luis Enrique.
PSG should master scoring without Kylian Mbappe, and the team is showing these signs that they can manage his exit from the club somehow if it happens in the near future. PSG scored three goals and that is enough to keep send them top of the table if Nice loose their game to Rennes today which PSG supporters and team will be hoping for, so that they can continue on the top. Next preparation for PSG is their champions league game against AC Milan, and they won this game strongly to be in the right mood for it.
That's how a team should be, they make the loads and work easier for everyone. Kylian Mbappe was unhappy I could see that from hais looks. He had chances but they opposing side made sure he was kept at bay. He still leads the league ¹ standing of top scorers with ¹⁰ Goals. Top talent, Real Madrid would be excited to have him.
