As a result, the Spaniard has divulged little information to his players ahead of Wednesday’s meeting with Basel, while looking to keep the assembled press guessing at his final training session.
He does have various options to consider Wednesday, which is helping to keep everyone on their toes, but Javier Pastore (calf) and Thiago Motta (glutes) will be missing for the French champions.
Looking at how PSG lined up during its final practice session, Adrien Rabiot and Hatem Ben Arfa could have a role to play, with both men in need of game time.
Emery could decide to keep the faith with those who have helped PSG to three successive victories, over Ludogorets, Bordeaux and Nancy, but he does have considerable experience at his disposal.
Angel Di Maria, Serge Aurier, Layvin Kurzawa and Maxwell were all missing over the weekend, but all four are back in contention after a period of rest.
