Both of them need points in the match considering their positions in the standings are equally unsafe, Bayern Munich has experienced 2 defeats in 4 matches and PSG has experienced 2 defeats and 1 draw from 4 matches if one of them loses I think it will be more difficult to qualify for the last 16, I think maybe PSG will lose in this match from any aspect I think Bayern Munich is superior in terms of performance and experience especially they play as the home team of course will be more favored by bookies.
Maybe the home team factor will affect Bayern Munich, but PSG also cannot be underestimated because if we look at the overall strength of these two teams in the Champions League match, I think it is very balanced and for the match between the two teams later, Bayern Munich and PSG also have the same motivation to be able to win the match, so I think for this match everything is still possible to happen and even if Bayern Munich is more favored, it will not be excessive.
Bayern Munich has good H2H record against PSG, but for now it is difficult condition to really be sure who will win and of course if Bayern Munich can take advantage of their advantage and win then it is only small score like 1 - 0 or just ends in draw and shares points.
Some big team in the UCL competition are indeed bit disappointing, many bad games and results have occurred for those big team who in the previous season always competed tightly.
