PSG are already on the edge of the Champions League elimination zone and will face RB Leipzig this weekend, so there is no need to expect much that PSG are still not worthy of advancing further. The Champions League seems too difficult for them.
Above PSG is Real Madrid who also have very little chance because they will face Atalanta. It makes sense why Madrid are considered to have little chance, in terms of performance they still can't promise anything and are now bottom of the standings in 24th position, so the match against Atalanta determines whether Madrid advances to the play-off round or out.

It is not Leipzig that PSG will face in the next match, but FC Red Bull Salzburg and this should be a match that PSG can win considering that in terms of team strength, PSG is the most favored in this match. and in the other two matches, PSG will face VFB and Manchester City. Hopefully PSG can give their best in the remaining 3 matches, so there is still hope to be able to enter the playoff zone.
And for Real Madrid, they will indeed face a fairly tough opponent, namely Atalanta, which is a fairly consistent team this season. And even though Real Madrid has a fairly good record when facing Atalanta, but seeing how Real Madrid is currently performing on the field, it is quite difficult to win this match. And I hope Real Madrid can give their best, I don't expect more, just hope this match ends in a draw.
