I didn't think that PSG would find themselves in such a situation that their further participation in the Champions League playoffs would be in doubt. Not all is lost yet, they should win, it seems that the opponent is not so strong, but PSG's attack this season is not as good as it was in previous years, apparently Enrique's decision to get by with the players he has in attack was not the best, or maybe he just did not receive approval from the management for funding to strengthen the attack.
I still think PSG will be able to qualify for the next round. But there is no doubt that it will be very difficult for PSG. Even so, I believe that PSG will be able to do this difficult task.
PSG is currently in 25th place in the points table and Madrid is in 24th place. If they can stay in the top 24 of the points table, PSG will be able to qualify for the playoffs. It is not very difficult to get into the top 24 of the table.
PSG's opponents in the next three matches are Salzburg, Manchester City and Stuttgart. Even if they cannot win against Manchester City, PSG has a chance of winning against Salzburg and Stuttgart. These two teams are not strong. However, if PSG cannot get 3 points in their next match against Salzburg, then PSG will probably not be able to stay in the top 24 of the table.
From the angle of playoff, it is highly possible that PSG will qualify because they will be meeting teams that are easier to win that the elite clubs that have not allowed them breath. But I don't have much confidence in PSG because of how the are going back and forth this season. Their last match against Auxerre was a very bad one in which they were not even to get a goal and end up playing a draw. If this small team can hold them, what will be their faith against big clubs from other leagues? When their name is a big so they are living on that big name but I doubt the name will be able to take them too far in the champions league.
They might win Manchester City but I'm not sure of Stuttgart and Salzburg because those are small times that will fight them like wounded lions. They have nothing to lose so they will give their best to play PSG.
