Defenders: Nuno Mendes, El Chadaille Bitshiabu, Danilo, Pembele
If you think this is not the greatest of defensive units, that's because it definitely is not. You're totally right, but that's also the current status of PSG and their absolute lack of depth in all positions, let alone the backline.
Other than Nuno Mendes and Danilo, and barring a surprising appearance of Sergio Ramos (let alone Marquinhos), things are looking awful for Galtier entering Sunday.
The manager will inevitably have to do with the crumbles of a unit that is depleted because of different injuries to players in all roles and positions. Yes, that includes right-backs Mukiele and Hakimi, and center-backs Kimpembe and Ramos/Marquinhos.
That leaves Galtier with two options for the left wing-back position (Mendes and Juan Bernat) and only one for the right wing-back: underdeveloped and struggling Timothee Pembele, expected to start again on Sunday. Another youngster, Bitshiabu, will man the middle of the line with not a single reserve fully fit and sitting on the bench.
