I don't think Salzburg and Stuttgart can be defeated easily because even though their performance is quite bad in UCL, PSG's performance is also not too impressive, besides PSG will face these two clubs as an away team which indicates that defeat can also be obtained by PSG, I see that for now their chances of qualifying through the play-off round are very slim, I wonder why a club as big as PSG can have difficulty in this competition, on the contrary in league 1 they dominate.
In my opinion, this match will be easy for PSG because they are stronger in term of strength and also the situation they are currently experiencing is quite different where they need to find a win to improve their ranking. Indeed, so far PSG performance has not been very good in the Champions League but against RB Salzburg of course Luis Enrique will pressure his players to play carefully to get 3 points.
The competition is getting more interesting because several teams continue to fight to enter the playoffs so that the game of several teams will be difficult to predict from their playing style. Psg only won 1 win in the Champions League this season where the win was obtained when they faced Girona and after that they found it very difficult to end the match by winning.
