For the next few matches, PSG will rely on several existing players. At least in Ligue 1, Enrique remains optimistic about winning. And for the UCL, I'm sure Enrique remains optimistic about doing his best.
According to information from psgtalk, up front, Ramos will be in the middle, the CF, Kvaratskhelia on the left, and Barca will be on the right. Ramos has sometimes been questioned because his performance hasn't been up to the coach's expectations, but here, Enrique must ensure he performs at his best.
The midfield and defense are still pretty much the same, except in goalkeeper, they now have Lucas Chevalier, since Donnarumma has left for Man City.
I am definitely something that is enough for them. They do not really need more to do anything, they just need to keep it going this way without dropping too much in quality. If they can do this, then they are going to do a lot better, so that's true.
I think it's clear that losing Doue and Dembele will be terrible for them and would prefer to have them both, but it's still not suddenly becoming a team that may lose towards some simpler teams during this week. They are strong enough all around to win all the games and won't get burned out that quickly. I am sure when the players come back, it's going to be even hard to fail the momentum they have. That is the most tricky situation, that will become the most important thing.
