I feel why there are no much speculation about Madrid against Salzburg is because Salzburg should be more easier for Madrid to win and also get a good the position as the make way in the next stage of the competition compared to that of Manchester city against PSG. PSG won't be an easy opponent but I seem to trust Pep's strategy more compared to Luis Enrique.
Besides Salzburg, Madrid has a match left against Brest, which I think is quite surprising in the Champions League. Brest managed to compete in 7th place in the standings, and even other strong teams are having quite a hard time. I hope Madrid can also overcome Brest to be more convincing and qualify for the next round.
While PSG and Man City may have to try hard for the remaining matches, Especially with the meeting of the two, it would be perfect to see both of them qualify for the next round, even though it has to be through the playoffs.
It will be quite difficult for both teams to get in unless their match ends in a draw. This season has brought many surprises, including in the Champions League. Because if the departure of PSG is not difficult to be surprised, the departure of Manchester City will be surprised by everyone, although from the point of view of the way they have been playing lately - there should be few surprises
