With the way Real Madrid is 24th and barely in, and PSG not even in right now, I have to say it's looking mighty difficult for them to do fine. Atalanta isn't a simple team neither, they just beat Milan this week, and I feel like this could be a difficult game for Real Madrid, with that many injuries, they may not end up winning, and that could put them out of top 24, and that's very disappointing, even with this many injuries, you would expect them to play better.
Thankfully the game after that is Salzburg, which shouldn't be too difficult to beat for them, unless they drop the ball and lose that too, but normally that looks like a simple enough to get a win. Last one will be Brest, who looked decent so far, but I still think they are weaker as well.
