Nuno Mendes and Timothee Pembele have returned to full training from muscular and knee problems this week, leaving the champions with four known absentees for the weekend's battle.
Neymar (ankle), Nordi Mukiele (hamstring) and Presnel Kimpembe (Achilles) are all recuperating from their season-ending injuries, while the luckless Renato Sanches is still missing with an adductor problem too.
Settling on a three-man backline in the business end of the season, Galtier should spring no surprises in defence, where Danilo Pereira, Sergio Ramos and Marquinhos will protect Gianluigi Donnarumma.
Juan Bernat registered an assist in last weekend's win over Angers but could now cede his spot to Mendes, as Achraf Hakimi continues unopposed on the right-hand side.
Marco Verratti was only given a cameo off the bench at the Stade Raymond Kopa, but the Italian should now come in for Carlos Soler alongside Vitinha and Fabian Ruiz in the engine room.
Fresh from setting a new all-time record for Ligue 1 goal contributions with a brace against Angers, Kylian Mbappe will resume his lethal partnership with Lionel Messi in the two-man strikeforce.
Messi turned playmaker to set up Mbappe's second last weekend, but the Argentine needs just one more goal to set a new overall record across Europe's big five leagues, currently level with Cristiano Ronaldo on 495 strikes apiece.
Paris Saint-Germain possible starting lineup: Donnarumma; Pereira, Ramos, Marquinhos; Hakimi, Ruiz, Vitinha, Verratti, Mendes; Mbappe, Messi
