The two main things Mauricio Pochettino needs to improve in October are the Messi-Mbappe-Neymar chemistry and the defensive play.
Seems like we've got a solution. First, let's take a look at the fixture list.
Oct 19: PSG vs RB Leipzig (Champions League)
Oct 24: Marseille vs PSG (Ligue 1)
Oct 29: PSG vs Lille (Ligue 1)
Here's our best eleven to win all these games.
Defence
The 3-4-3 switch could finally get the best out of both Achraf Hakimi and Nuno Mendes as they won't need to track back all the time.
The three-at-the-back system would also let PSG cement their backline, with Abdou Diallo finally being used in his natural position.
Midfield
You may think it's way too defence-minded but don't forget that Marquinhos could act as a deep-lying playmaker while Leo Messi would definitely drop deeper to help the midfield.
What we've got here is a great balance of quality defending and solid playmaking, with Leandro Paredes' underrated long passes being used as a secret weapon.
Attack
Given Messi's playmaking role and the wing-backs' attacking output, we would basically have two players upfront – Neymar and Kylian Mbappe.
If the two improve their finishing ahead of the upcoming fixtures, the Parisians will take it all.
